asked on Server 2012 AD Migration - Is this allowed?
We were about to install a new Server 2012 and the historic SBS 2008 died the day before.
The original server was on Domain ABC1 and the new server will be on ABC2.
Can I add the PC to the new Domain as I can't contact the old server to remove them properly.
I have run a test and it appears to work but is still using the old DHCP, the IP number and ranges are effectively identical.
All data, per se, has been saved.
Many thanks

The problem was that as it couldn't contact the original DC it was complaining.
Can I just swap one domain for the other, with the new DC in place?
Or should I go old domain > workgroup > new domain.
Is this what you call a disjoin?

apparently your only choice .. no backups? even to restore the domain to a virtual machine?

Yes this can be done and it works: Well I have several dozen machines working perfectly having done it this way.
The rule of thumb is:
1. Make sure you have or have rest the local admin password on that machine and you have a record of the machine name, the admin name and password.
2. Join the new domain. You will get an advisory message - continue. There is a longer version of the message which means you have forced the DNS in which can make the DNS auto-detect and try again.
3. Enter the new domain's admin username/admin combo.
4. Restart and done.

To remove a system from a do in you do not need the DC. (Properties of computer, advanced settings, computer name, change to workgroup to disjoin) or rerun the wizard to join the new domain.
