Microsoft ecosystem migrations

Leading Microsoft Ecosystem Migration Experts

Move into Microsoft with control. We help organizations migrate from legacy systems, on-premises SharePoint, file shares, Nintex, InfoPath, SharePoint Designer, Google Workspace, Box, Dropbox, and other Microsoft 365 tenants into a cleaner, governed Microsoft environment.

What we migrate

Migration work is rarely just “copy the data.” We plan the destination, resolve hidden blockers, preserve what matters, retire what does not, and leave your team with a Microsoft environment they can actually operate.

  • Microsoft 365 tenant-to-tenant migrations
  • SharePoint Server to SharePoint Online migrations
  • File share, Box, Dropbox, OneDrive, Teams, and document library moves
  • Exchange Online migration and cutover planning
  • InfoPath, Nintex, and SharePoint Designer modernization
  • Power Platform and Azure migration enablement

Our migration method

Assess

Inventory content, identity, permissions, workflows, integrations, customizations, data volume, compliance needs, and business-critical paths.

Architect

Design the target tenant, SharePoint information architecture, Teams and OneDrive patterns, security baseline, and governance model.

Remediate

Fix blockers before the move: stale permissions, unsupported customizations, workflow dependencies, ownership gaps, naming conflicts, and retention issues.

Pilot

Run pilot migrations, validate mapping decisions, confirm user experience, test rollback paths, and refine communications.

Cut over

Execute phased moves with clear go/no-go gates, business validation, issue tracking, and defined escalation paths.

Stabilize

Provide hypercare, admin handover, documentation, governance tuning, and post-migration operational support.
