Since the primary DC is down/offline we can't transfer the roles to another DC. How would one do this?

If your PDC is offline and cannot bring online please seize the roles.

Please be very careful while doing this,  one mistake can spoil your entire domain.

Once you finished seizing the roles please install additional domain controller to be safe.

Is this DC ever coming back online? It is only recommended to perform a Seize of the FSMO roles if the DC will NEVER come back online. If this is the case then proceed. However if you have any last bit effort that you can get the DC online for 10 minutes then I would transfer the roles gracefully, if possible.

Will, possibly. The primary one has AD database corruption. If we restore that DC from the latest backup how would it affect the other DCs (replication/accounts) would it be best to seize the role rather than restoring from a backup that's several hours old?

Not sure how you've diagnosed an AD database corruption...

If that DC is corrupt, I would seize the roles to another DC.  Then delete that DC from AD (including a metadata cleanup if necessary - newer DCs can do it automatically).  Then I'd rebuild it.

In general, I avoid restoring DCs when one fails... in my opinion, it's safer to just rebuild.

If getting the currnet FSMO role holder online at any chance try and transfer the roles gracefully. If not then your only option is to Seize the roles.

BTW: If you expect or suspect you MIGHT EVER bring the failed system back online, do NOT seize the role!
