Delta-sync methodology
Data syncs incrementally ahead of cutover, so the final switch is small and fast, not an all-night event.

Microsoft 365 Migration Services for a Smooth, On-Time Transition
Most migrations don't fail because of the technology. They fail because identity and permissions get mapped halfway throug h instead of before anything moves. We map it first.

Features
Features and Capabilities
A successful migration depends on choosing the right moment, not just the right tools. Here's what keeps a Microsoft 365 migration running the way it's supposed to, from the first identity check to the moment the last mailbox lands safely on the other side.
Identity and permission mapping
Entra ID mapping happens before migration starts, not after something's already missing.
Legacy Exchange migration
Moving off on-prem Exchange or an older platform, handled without losing mail flow along the way.
Tenant consolidation support
Merging environments after an acquisition, without losing what's already there.
Data integrity validation
Every stage gets checked before the next one starts, not just at the very end.
Post-migration optimization
The environment gets tuned after go-live, not left exactly as it landed.
Other offerings
Migration Service offerings
Every migration we run follows the same disciplined sequence: assess first, map identity early, sync data incrementally, and validate everything before the old environment gets switched off for good. Here's exactly what's included once you bring us in.

Migration readiness assessment
A clear picture of your current environment before we scope anything.
Delta-sync migration execution
Incremental syncing that keeps the disruptive part short.
Identity and permission mapping
Access levels carry over instead of getting rebuilt from scratch.
Mailbox and license migration
Every account moved and verified, not just bulk-transferred and hoped for.
Data validation checks
Staged validation catches problems while they're still small.
Post-migration support
We stay past go-live to fix what only shows up once people are actually using it.
Why XDuce
Why Choose XDuce + DEV IT
A Microsoft 365 migration should feel like a planned move, not a gamble. XDuce and DEV IT work as one accountable team with a documented process and the capacity for large tenants, so your people keep working while we move.
Documented delta-sync method
Our documented delta-sync method keeps cutover short. Partner-led migrations hit time and budget 71% of the time, DIY only 49%.
Identity mapped first
We map identity and permissions before day one, so the hardest part of any migration never ambushes you mid-project.
Two firms, one team
XDuce plans, DEV IT builds, and you deal with one accountable team from start to finish.
Scope in writing from day one
Scope is documented before we start. You’ll know what’s included, what isn’t, and who owns what.
Minimal disruption by design
Staged validation and delta-sync keep the cutover window small, so your teams keep working while we move.
Support beyond go-live
We don’t leave at cutover. We stay to fix what only shows up once people are working in it.

Depends on data volume and complexity, but delta-sync methodology keeps the disruptive part short regardless of size. Most of the work happens before cutover, so the final switch is usually hours, not a weekend everyone has to brace for.
Our approach targets minimal disruption through delta-sync and staged validation. That's our delivery standard, not an industry-wide guarantee, since every environment carries different risk depending on size and complexity.
They're mapped in Entra ID before the move and validated against the destination, so access carries over instead of getting rebuilt. It's the step DIY migrations tend to rush, and the one that causes the most issues afterward.
Strongly recommended. Skipped assessments are one of the most common reasons migrations run over budget or timeline, since legacy dependencies and undocumented integrations tend to surface mid-project instead of being caught on paper beforehand.
Identity and permission complexity, more often than the data transfer itself. Years of ad hoc access changes and shared mailboxes are usually the part nobody scoped properly, not the mechanical work of moving data from one place to another.
