Why Enterprise Migrations Fail (And How to Prevent It)

Avoiding Disaster

Migrations fail due to a lack of Discovery. The three main culprits are:

1. Undiscovered Data Hoards: Finding out a single user has a 200GB mailbox on the night of the cutover will destroy your timeline. Run deep audits weeks in advance.
2. Corrupted Source Data: Legacy On-Premise Exchange servers often contain corrupted items that API extraction tools cannot read.
3. Poor Change Management: If the IT team perfectly migrates the data, but the end-users don't know how to log in to Gmail on Monday, the business views the migration as a failure. Communication is just as important as engineering.
