Q. Can I rename my Azure AD Sync (AADSync/DirSync) Server?
A. Behind the scenes Azure AD Sync (AADSync/DirSync) leverages Forefront Identity Manager (FIM) which does not support a server rename. If you want to rename your AADSync/DirSync server then the process would be:
- Uninstall AADSync/DirSync
- Rename the server
- Reinstall AADSync/DirSync
