[Samba] Raise Domain Level, Forest Level and Schema for Bitlocker integration

[Paul Littlefield]

Hello,

I would like to add BitLocker integration to the three DCs we have running 4.15.13 on Ubuntu 22.04 LTS.

The DC has been around a while and is currently on Schema version 47 and Domain level 2008_R2.

Can I confirm that the procedure to upgrade the three DCs is as follows:-

1) backup
2) upgrade domain and forest to latest 2012_R2
3) upgrade the schema to latest 2012_R2

Also, in what order of DCs should I perform these changes?

DC5 (FSMO Role)
DC6
DC7

Thanks,
