Hello,
I want to upgrade my domain controller from 16 to 17 to solve windows 11 join AD problem, so where can I find a full documentation how to upgrade it and migrate all data from my current server
Thanks
Forum:
Here's how I switched my domain to V17
The steps I used are:
It's always best to backup before doing anything. I borked this process and luckily was able to restore my LXCs from the backup and try again. Still have the backups, but so far so good...
If you decide to try this, let me know whether it worked for you as well or not.
One quirk: you need to manually remove the RID set node
When you try to delete the old DC1 (which should be a regular domain member rather than a domain controller after you demote it) you may get an error:
This is because the entry has a sub-node in LDAP that is called "RID Set" (a set of RIDs is assigned to each domain controller and it does not get deleted when you demote the server).
I simply manually deleted that using Apache Directory studio and then retried the command which worked without issues.
Details are in this thread of the samba mailing list: https://lists.samba.org/archive/samba/2023-May/245300.html
