Are you running a MigrationWiz AD migration with engineers certified only on M365 workloads and running into sAMAccountName mapping failures?

I hold both BitTitan certifications: MigrationWiz for Microsoft 365 and MigrationWiz for Active Directory. They are separate credentials for a reason. The mechanics differ enough to justify distinct training.

Mailbox migrations typically match source and destination objects using UPN or SMTP address. AD object migrations match on sAMAccountName. In acquisition scenarios, the source and target domains often use different naming conventions, and without a custom mapping CSV, object matching fails across the board.

For MigrationWiz AD migrations, the mapping file is a two-column CSV: source sAMAccountName in column one and destination sAMAccountName in column two. There is no header row, and the column order is fixed. If you reverse the order, MigrationWiz attempts matches in the wrong direction, which can lead to silent skips or incorrect mappings.

Are you building a custom sAMAccountName mapping file before running your first MigrationWiz AD batch?
