Migration preparation checklist

Find unanswered decisions and missing preparations before moving spreadsheet records into another system. Export your checklist.

All seven preparations are unanswered. Confirm each item above to find specific gaps.

  • Name the owner and correction authority for each target field.
  • Record required fields, date formats, units and allowed values in the field map.
  • Agree the stable record identity and how duplicates or corrections are handled.
  • Record source counts and the checks for missing, extra or changed records.
  • Test valid, missing-field, duplicate and format-error records; check the results.
  • Agree when source edits stop and how late changes will be carried over.
  • Name the rollback decision owner and test restoring the agreed recovery copy.

This map is an example, not a supported import format for a named product. Check your target’s actual field types and import rules. Keep a reference to the source row so a rejected record can be corrected without losing its identity.

Turn each gap into a named task

A team has documented field owners and formats but has not tested a duplicate import or agreed a freeze window. How should the checklist be answered?

Show the worked answer

Mark ownership and formats as defined and checked. Mark the test import and freeze window as not ready. Leave other unverified items unanswered; the result lists their specific follow-up tasks without a readiness score.

An all-yes result only means no gaps were reported for these seven items. It does not establish production safety, access control, backup completeness or compatibility. Verify the actual dataset, target system and recovery exercise before a cutover decision.
