You've seen it before. A migration project starts with good intentions: a spreadsheet to track applications, a shared folder for documentation, and a group email thread to keep everyone aligned.
Then reality hits.
Version conflicts. Missing updates. Forgotten dependencies. A critical app migrates before its database is ready. The DSI asks for a status report and nobody has the same numbers.
By phase three, the spreadsheet has 47 tabs, the email chain is 200 messages deep, and your team is firefighting instead of migrating.
