If you want to go the very save way, shutdown Samba on all your DCs and
take an offline backup. Then you have a domain wide consistent backup
and if something goes wrong, you can reset to this state on all DCs.

However as longer the DCs are up after the update, as more could have
changed inside the directory. Even if you don't create users, etc.,
things may change in the background, like machines change their
password. If you reset your DCs then, those machines need to be rejoined
to the domain.

Depents on your network. E. g.
- check if directory replication
- check if member server retrieve the accounts from the DCs
- check kerberos
- domain logon
- roaming profiles
- etc. - it really depents what services you're providing
