A Strategy Per Workload, Not One Plan For Everything

Cloud Migration With the Rollback Plan Written Down First

Cloud migration done as a method rather than a lift. Each workload gets one of the six migration strategies — rehost, re-platform, refactor, repurchase, retire or retain — chosen on evidence from discovery and written down.

At a glance

Every phase has a cutover window, a named person who can stop it, and a rollback path that was tested rather than assumed.

Egress charges, license portability and target run cost are modeled before the project starts.

This is the platform-agnostic methodology page for Houston, The Woodlands and Spring businesses; the platform choice itself is a separate question and we link to it.

What We Offer

Comprehensive solutions tailored for Houston-area businesses

Discovery and Application Inventory

Before any strategy discussion, we build the inventory: every server, application, database and integration, with its owner, its dependencies, its license terms and how much data it holds. Houston businesses routinely discover applications nobody had on a list. Finding those now is cheaper than finding them at cutover.

A Migration Strategy Per Workload

There is no single answer for an estate. Each workload is assigned one of the six strategies — rehost, re-platform, refactor, repurchase, retire or retain — based on its business value, its technical debt and what it would actually cost to change. The reasoning is written down, so the choice can be revisited rather than re-argued.

Server and Workload Migration

Physical and virtual servers moved to cloud infrastructure with the dependency order established in discovery. The Woodlands companies modernise without rebuilding from scratch, and workloads that are not ready to move stay where they are until they are.

Data Migration With Verified Counts

Databases and file storage move with reconciliation on both ends: record and object counts compared source to target, checksums where the platform supports them, and a written variance report before cutover is approved. Spring businesses sign off on a number, not on an assurance.

Cutover Windows and Rollback

Every cutover has a defined window, a named person who can call it off, a documented decision point for invoking rollback, and a rollback path that has been tested rather than assumed. Migrations that cannot be reversed are the ones that turn a bad night into a bad quarter.

Cost and License Modeling

Before you commit, the model covers target-platform run cost, one-time data transfer charges, what your existing on-premises licenses can and cannot carry across, and what has to be repurchased. Licensing and egress are the line items most often missed when a move is costed.

Platform-Agnostic Target Selection

We are not trying to land you on a particular platform. The selection is driven by where your applications already run well, what your team can operate, and what the run cost looks like at your actual usage. See our Azure vs AWS vs GCP comparison for how that decision is usually made.

Security and Identity Configuration

Identity, access control, encryption, logging and network segmentation are configured as part of the migration rather than retrofitted after it. A workload that arrives in the cloud with its on-premises assumptions intact is the standard way a migration creates an exposure.

Disruption You Planned For

Parallel running, data synchronization and off-hours cutover keep the outage inside a window agreed in advance. Houston businesses know the date, the length and who can stop it before it starts.

A Reversible Plan

Each phase has a rollback path with a documented trigger. If validation fails, the decision to revert is made against pre-agreed criteria rather than invented at 2am by whoever is still on the call.

The Bill Is Modeled Before You Commit

Egress charges, license repurchasing and target run cost are modeled before the project starts. The Woodlands finance teams see the total cost of the move and the ongoing cost of the destination, separately.

Workloads That Should Not Move, Do Not

Retain and retire are real answers. Applications with hard latency requirements, unsupported architectures or a decommission date inside the year are handled accordingly instead of being dragged into the cloud out of consistency.

Technical Debt Left Behind Deliberately

Migration is the one moment when rebuilding a bad configuration is cheap. We flag what should be redone versus copied, so you move practices worth keeping rather than everything that happened to be running.

The Six Migration Strategies

Known in the industry as the 6 Rs. The choice is made per workload, not per company, and most real estates end up using four or five of them. Each one trades effort against what it buys you.

Rehost

Lift and shift

Right call when hardware is aging out, a lease or data-center contract is ending, or the deadline is fixed and the application works fine as it is.

Lowest effort and lowest project risk. Buys you off the hardware and nothing else — inefficiencies move with the workload and you now rent them monthly.

Re-platform

Lift and reshape

Right call for self-managed databases, web tiers and middleware where a managed equivalent exists and the application can point at it with configuration rather than code.

Moderate effort concentrated in testing. Buys back patching, backup and failover as platform duties instead of your team’s.

Refactor

Rearchitect

Right call only where the application is strategic, actively developed, and constrained by its current architecture in a way the business can feel.

Highest effort and highest risk by a wide margin, and it needs developers, not just infrastructure. Buys elasticity and a lower unit cost at scale. Rarely worth it for a stable line-of-business application.

Repurchase

Move to SaaS

Right call when a commodity SaaS product covers what a customized legacy application does, and the customization is no longer a competitive advantage.

Effort moves from engineering to data migration, integration and change management. Buys you out of maintaining the application at all, at the price of a subscription and reduced control.

Retire

Switch it off

Right call for anything discovery finds with no active users, no owner, or a function another system already performs. Almost every estate has some.

Negative cost — it removes license, support and migration effort. The work is confirming it really is unused and capturing an archive before it goes.

Retain

Leave it where it is

Right call for workloads with hard latency requirements to on-site equipment, unsupported architectures, license terms that do not permit cloud hosting, or recent capital investment with useful life remaining.

No migration cost, but it commits you to a hybrid estate. Plan the connectivity and identity between the two sides deliberately rather than leaving it as a leftover.

What Goes Wrong, and the Plan For It

Cloud migrations rarely fail on the copy. They fail on licensing, on egress nobody modeled, on an application that could not move, and on a cutover with no named owner. These are planned for in writing before the first workload moves.

No Tested Rollback Path

A rollback that exists only as an intention is not a rollback. Ours names the trigger condition, the person who can call it, a time box on troubleshooting before it is called, and how data written to the new platform during the window gets reconciled back. The pilot phase is where it is tested, on non-critical workloads, before it is needed.

Egress and Data-Transfer Costs

Providers generally charge to move data out, not in, so the cost of the migration itself is rarely the problem. The problem is the architecture you leave behind: cross-region chatter, backups written outside the provider, analytics reading directly from cloud storage. Modeled during design against your real data flows, because it is a recurring bill.

License Portability

Outright-purchased licenses with active support sometimes carry to cloud; OEM, bundled and some volume-agreement licenses frequently do not, and per-core database licensing rarely maps cleanly to cloud core counts. Reviewed during assessment so repurchasing appears in the budget rather than in an audit.

Legacy Application Incompatibility

Hardware dongles, licenses tied to a MAC address, unsupported operating systems, hard-coded IP addresses and latency requirements to equipment on your own site. Discovery finds these; the 6 Rs assessment decides whether they mean re-platform, repurchase or simply retain.

Cutover Sign-Off With No Owner

Someone has to be able to say go and someone has to be able to say stop, and it should be the same named person, agreed in writing, available during the window. Cutovers that stall do so because the decision had no owner, not because the technology failed.

What Reversal Actually Costs

Reverting the infrastructure is usually straightforward. Reconciling the transactions users entered on the new platform before the decision was made is not. That is why the source stays online read-only until acceptance, why the window has a hard time box, and why the rollback decision point sits early in the window rather than at the end of it.

Frequently Asked Questions

What are the 6 Rs of cloud migration?▼

Six strategies, one chosen per workload. Rehost means lifting the workload as-is onto cloud infrastructure. Re-platform means making targeted changes — usually moving a self-managed database onto a managed service — without rewriting the application. Refactor means rearchitecting the application for cloud-native services. Repurchase means dropping the application and buying a SaaS product that does the job. Retire means switching it off because nobody has used it in eighteen months. Retain means deliberately leaving it where it is. Most real estates end up using four or five of the six.

How do you decide between lift-and-shift and re-platforming?▼

By what the workload is worth changing. Rehosting is the fastest and cheapest path off ageing hardware and it carries the least project risk, but it also carries your existing inefficiencies onto a platform where you now pay for them monthly — an oversized VM stays oversized. Re-platforming costs more engineering time up front and buys back operational effort afterwards, which is why self-managed databases are the most common candidate. The usual test is whether the workload will still be running in three years and whether its run cost is meaningful. Short-lived or cheap workloads get rehosted; long-lived expensive ones justify the re-platform.

What does a realistic cutover window look like?▼

It depends entirely on data volume, acceptable downtime and whether the application supports replication. A file server with continuous sync ahead of time can cut over in a maintenance evening, because the final delta is small. A large transactional database with no replication path needs a quiesce, a final copy and a verification pass, which is usually a weekend. Applications with hard integration dependencies have to move in a group, which lengthens the window. The honest version is that the window is sized during the pilot, from the measured copy rate of your actual data, not estimated from a template at proposal stage.

What is in a rollback plan, and when would you invoke one?▼

A rollback plan names the condition that triggers it, the person authorised to call it, the maximum time the team spends troubleshooting before calling it, the technical steps to revert, and how data written to the new platform during the window is reconciled afterwards. The trigger is agreed before the cutover — typically failed validation of a defined checklist, or the window elapsing with the service still degraded. The hard part is not the technical revert; it is the data written after the cutover point, which is why the source system is usually kept online but read-only until the new platform is accepted.

What are data egress costs and when do they bite?▼

Most cloud providers charge little or nothing to move data in and charge per gigabyte to move it out. Getting into the cloud is therefore rarely where egress hurts. It bites in three places: migrating between cloud providers later, pulling large datasets back on-premises for processing or archive, and architectures that route traffic out of the provider network in normal operation — chatty cross-region designs, backups written to a third-party target, or an analytics tool reading directly from cloud storage. We model egress against your actual data flows during design, because it is an ongoing run cost, not a one-time migration line item.

What happens to our existing on-premises licenses?▼

Some carry, some do not, and the terms vary by vendor and by how you bought them. Licenses bought outright with active support sometimes have portability rights for cloud use; licenses bought through a volume agreement, an OEM channel or bundled with hardware frequently do not, and dedicated versus shared tenancy can change the answer for the same license. Database and per-core licensing is where this most often goes wrong, because cloud core counts rarely map cleanly to the on-premises entitlement. The license review happens during assessment so what has to be repurchased appears in the budget before the project starts rather than in an audit afterwards.

Can you migrate our legacy applications?▼

Usually, and the answer for each one comes out of the 6 Rs assessment. Many legacy applications rehost without modification. Some have hard dependencies — a license tied to a MAC address, a dongle, an unsupported operating system, or a latency requirement to equipment on your factory floor — and for those, retain is often the correct answer for now, with a repurchase or refactor planned separately. We would rather tell you an application should stay put than move it and manage the consequences.

Do we have to move everything at once?▼

No, and hybrid is a legitimate end state rather than an unfinished migration. Workloads with regulatory constraints, hardware dependencies or recent capital investment can stay on-premises while the rest moves, connected over a site-to-site link or private interconnect. The thing to plan for deliberately is the connectivity and identity between the two, because a hybrid estate where authentication or name resolution was an afterthought is harder to support than either side alone.

How do you verify nothing was lost?▼

Counts and checksums, compared and written down. For file data we reconcile object counts and total bytes source to target, and use checksum comparison where the storage platform supports it. For databases we compare row counts per table and run application-level validation against agreed test cases. A variance report goes to whoever signs off before cutover is approved, and the source system stays available read-only for an agreed retention period after the move so anything discovered late can still be retrieved.

How do you handle data security during the migration?▼

Data in transit is encrypted, transfer credentials are scoped to the migration and revoked afterwards, and access to the migration tooling is logged. Encryption at rest is configured on the target before data lands, not after. Where the migration involves regulated data, we document the chain of custody, and copies staged on intermediate media or storage are tracked and destroyed on a schedule rather than forgotten.

What training will our staff need?▼

Two audiences with very different needs. IT staff need the operational model for the target platform — how to monitor it, patch it, restore from it, and read the bill, because cost management becomes an operational duty in a way it never was with owned hardware. End users usually need very little if the migration was rehost or re-platform, and considerably more if a repurchase replaced an application they used daily. We document both and deliver the sessions as part of the project rather than as an upsell.

Which cloud platform should we choose?▼

This page is deliberately platform-agnostic, because the methodology is the same whichever destination you land on. The choice comes down to where your applications already run well, which identity platform you already operate, what your team can support without hiring, and what the run cost looks like at your real usage rather than at list price. Our Azure vs AWS vs GCP comparison walks through that decision for mid-sized businesses, and our Azure managed services page covers what ongoing operations look like once you are there.

Do you provide Cloud Migration in Houston and nearby areas?▼

Yes. LayerLogix is based in the Greater Houston area and delivers cloud migration to businesses across Houston and the surrounding communities, including The Woodlands, Spring, Katy, Sugar Land, Conroe, Cypress, and Pearland. For most Houston-area clients we can be on-site the same day when something needs hands-on attention, and our help desk is available during business hours, with after-hours emergency support. Call 713-571-2390 to check coverage for your specific address.

What does Cloud Migration cost for a Houston business?▼

Cloud Migration is quoted per project rather than as a monthly fee — the price is driven by the scope of the work, the number of devices, sites, and users involved, plus any equipment, design, configuration, and testing effort. We start with a free, no-obligation assessment, then give you a clear, itemized quote in plain English with no hidden costs — so you know the full price before any work begins.
