Compatibity tool prompts for ADPREP when upgrading windows server from 2003 to 2008 R2 domain
Trying to upgrade windows 2003 domain controller ( single server ) I kept getting prompted to upgrade my AD :
Ended up that I had to :
- switch to native mode.
- run forestprep AND domainprep
After that, all was well. hope it saves someone some time.
