What We Offer

Comprehensive solutions tailored for Houston-area businesses

Mailbox Migration

Migrate Exchange Online mailboxes between tenants with full fidelity—email, calendars, contacts, and permissions transfer intact. Houston businesses keep operations running during M&A transitions.

SharePoint & OneDrive Transfer

Move SharePoint sites, document libraries, and OneDrive data across tenants while preserving metadata, versions, and permissions. The Woodlands companies consolidate without losing institutional knowledge.

Domain Transfer & Coexistence

Coordinate domain cutover between tenants with mail flow coexistence during transition. Spring businesses maintain email delivery for both organizations throughout the migration window.

Teams & Groups Migration

Transfer Microsoft Teams channels, conversations, files, and Microsoft 365 Groups to the target tenant. Katy companies preserve team collaboration history and structures.

Identity & License Planning

Map user identities across tenants, plan license assignments, and configure Entra ID for the merged organization. Houston businesses avoid duplicate licensing costs and identity conflicts.

Post-Migration Cleanup

Decommission the source tenant, remove stale objects, consolidate security groups, and validate every migrated user. Sugar Land organizations start clean in their unified environment.

Why Choose LayerLogix?

Serving businesses throughout the Greater Houston area including Houston, The Woodlands, Spring, Katy, Sugar Land, Conroe, Pearland, Dallas, Austin.

Accelerate M&A Integration

IT integration is often the longest phase of a merger. Structured tenant migration compresses the timeline so acquired companies operate under one roof faster.

Zero Mail Disruption

Coexistence and mail flow routing ensure employees send and receive email without interruption throughout the migration, no matter which tenant they are in.

Preserve Business Data

Every email, document, Teams conversation, and OneDrive file migrates with full fidelity. No data loss, no missing history, no broken links.

Consolidate Licensing Costs

Running two M365 tenants doubles licensing spend. Consolidation eliminates redundant subscriptions and simplifies vendor management.

Unified Security Posture

A single tenant means one set of conditional access policies, one DLP configuration, and one security baseline instead of maintaining two separate environments.

Frequently Asked Questions

How long does a tenant-to-tenant migration take?▼

A typical Houston business with 100-500 mailboxes and moderate SharePoint data completes migration in 4-8 weeks. The timeline depends on data volume, complexity of SharePoint structures, and coexistence requirements during the transition.

Will employees experience email downtime during migration?▼

No. We configure mail flow coexistence between tenants so email routes correctly throughout the migration. Mailbox cutover happens per-batch with users typically seeing only a brief Outlook reprofile that takes a few minutes.

What happens to shared calendars and distribution lists?▼

Distribution groups, shared mailboxes, and resource calendars are migrated as part of the mailbox phase. Cross-tenant calendar sharing is maintained during coexistence so meeting visibility continues.

Can you migrate Teams chat history?▼

Teams channel messages and files migrate to the target tenant. One-to-one chat history has limitations due to Microsoft API restrictions, but we preserve channel conversations, shared files, and team structures.

Do you handle migrations for acquisitions of companies outside Houston?▼

Yes. Tenant-to-tenant migration is cloud-based so location is irrelevant to the technical work. We manage migrations for Houston-headquartered companies acquiring businesses anywhere in the country.

What about third-party apps connected to the source tenant?▼

We inventory all enterprise applications, OAuth consents, and service principals in the source tenant. Each integration is re-established in the target tenant as part of the migration plan.

How do you handle conflicting security policies between tenants?▼

We audit conditional access, DLP, and compliance policies from both tenants and design a unified policy set for the target. Houston businesses get a single consolidated security posture that meets the stricter of the two environments.
