# Does a successful spreadsheet import prove migration readiness?

**No: test the specific import route and the records it omits.** IBM’s OpenPages 9.1.x FastMap documentation says that FastMap cannot import attachments or signatures and cannot preserve system creation-date information through that process. This is a limitation of that documented route—not proof that all alternative migration methods are unavailable. ([ibm.com](https://www.ibm.com/docs/en/openpages/9.1.x?topic=fastmap-overview&utm_source=openai))

For a **ServiceNow IRM vs Archer vs IBM OpenPages** evaluation, our proposed test is identical: migrate a small, deliberately difficult record set containing a historical approval, restricted attachment, retired owner and cross-entity relationship. Require each supplier to explain its supported method and unresolved gaps. Do not score a CSV upload as a complete exit-and-replacement rehearsal.
