An integration exchanges information between systems; a migration moves information into a new home. A project may need both, but they involve different decisions. Plan what each system owns, how records are matched, and who checks the result before treating the connection as a completed feature.
Identify the information and its owner
List the records involved and which system is authoritative for each. A customer name, approval status, and invoice reference may have different owners. Decide whether information travels once, on a schedule, or after a particular event.
Include the business person who understands the records and the administrator who controls each system. Confirm that the available connection supports the required action; access to a product does not automatically include every integration capability. Put uncertain behavior into the project brief for investigation.
Map meaning as well as fields
Matching column names is only part of the task. Discuss dates, statuses, identifiers, missing values, duplicates, and relationships between records. Determine whether old information should be moved, archived, or excluded under the business’s approved requirements.
| Mapping decision | Question to settle |
|---|---|
| Identity | How is the same record recognized in both systems? |
| Status | Do the labels mean the same thing? |
| Missing values | Reject, review, or apply an agreed default? |
| Relationships | How are records linked after transfer? |
Use a limited set of approved sample records to review the rules. Keep transformations documented so the business can explain why the destination looks different from the source.
Plan failures and validation
Ask what happens when a connection is unavailable, a record is rejected, or an operation is attempted again. The technical design should account for duplicate processing and make failures visible to someone responsible for resolving them.
For migration, compare expected records and important relationships with the destination, then exercise representative tasks in the application. Microsoft’s migration guidance calls for validation after migration; the exact checks depend on the data and platform. A transfer completing without an error is not the same as business acceptance.
Agree the cutover and recovery decision
Define when the old process stops accepting changes and how changes made during the transition will be handled. Identify the person who approves the switch and the evidence they need. Avoid allowing users to unknowingly maintain two competing versions of the same information.
Discuss recovery before the live move, including what happens to new records created after cutover. Keep the old system’s treatment explicit rather than deleting information as an informal cleanup step. Use the deployment checklist to connect these decisions to launch approval.
