Run DCDIAG and make sure the DC passes all the tests. Resolve any issues found before going ahead.

I generally don't advise it. But if it is just a DC then you can usually do so safely. The things to consider mostly revolve around DNS. If clients are using it. If there are trusts or stub zones elsewhere.

If other roles coexist in the same OSE then that changes considerably and the possibilities are too numerous to possibly cover.

Note that the DC can also be a DNS server, so if that DNS address is used elsewhere, such as DHCP server, then the IP needs updting in the DHCP Server/Scope options and on any static IP configured servers/devices.
