Read guideFour decisions every migration needs
Choose a route
Confirm the source, destination and supported workload.
Prepare access
Check permissions, licensing, quotas and destination accounts.
Map resources
Connect each selected source user to an explicit destination.
Pilot and verify
Migrate a representative sample and review the evidence.
From source authentication to migration results
ElephantsData guides operators through project setup, source and destination authentication, resource mapping, preflight, scheduling and results. Only selected users and workloads enter a migration batch.
- Explicit user and resource mapping
- Readiness findings before transfer
- Checkpoints, retries and per-user progress
- Reconciliation reports and exceptions

Supported does not mean identical at the destination
Provider licensing, API limits, permissions, destination quotas and tenant policies still apply. Native metadata, links, sharing models, email rules or photo albums may need separate treatment depending on the route.
- Review reconciliation and exceptions.
- Ask pilot users to verify the destination.
- Keep an independent backup.
- Complete a latest-changes pass when supported.
