ERP data migration moves selected business records into a new or changed system while preserving their meaning. Zoha helps Ethiopian teams define the records, clean agreed fields, test imports and reconcile the result. The project needs a clear starting position and a transition plan, not just a file that the new system will accept.

Decide what needs to move
Separate active master records, opening positions and historical transactions. Each serves a different purpose and requires different checks. A buyer may need current suppliers and available stock immediately while older detail remains in a controlled archive.
Ask who uses the history and what question it answers. Moving every old transaction can add substantial cleanup and reconciliation work. Leaving important history inaccessible can also create problems. Record the decision rather than treating a complete export as the automatic migration scope.
Write the mapping before the full import
| Source item | Mapping decision | Check |
|---|---|---|
| Customer reference | Keep or replace the identifier | Relationships still point to the right account |
| Item quantity | Agree the unit and location | Converted quantities reconcile |
| Category | Match to a controlled destination value | Unmatched categories appear in exceptions |
| Opening position | Define the agreed starting date | Business owner confirms the starting record |
Keep a record of transformations. If two source fields become one destination field, the buyer should understand what information is being combined or left behind.
Resolve uncertainty before it becomes system data
A migration often reveals duplicates, obsolete records and unexplained values. Some can be corrected using a written rule; others need business knowledge. Keep the second group in an exception file with a specific question and owner.
For a hypothetical stock list, a product may appear in both boxes and individual units. A quantity comparison is meaningless until the unit relationship is agreed. The migration should preserve that decision in the mapping rather than hiding it inside a one-off spreadsheet formula.
Rehearse the move using the checks that matter
- Import a representative sampleInclude varied records and known exceptions, not only the cleanest rows.
- Test relationships and tasksOpen related records and perform the workflows that depend on the imported information.
- Reconcile the resultCompare counts, key quantities and the agreed starting positions with the source.
- Review the transitionDecide when old entry stops, how late changes are captured and who can postpone the move.
Keep a recoverable source copy and document what would trigger a rollback. A successful technical import is only one acceptance check.
Leave a traceable starting point
The handover should include the final mapping, source references, reconciliation results and unresolved exceptions. Staff need to know which records are complete and which still require a decision. Document the last source update included in the move.
After transition, review discrepancies through a named process rather than allowing untracked manual corrections. That makes it possible to distinguish a migration problem from a new operating error and to protect the reliability of the first reports.
