Installing WSE 2016 onto an existing domain that has a peer DC

Is there a migration guide available that covers these steps:

  1. Installing Server 2022 Standard as a peer DC (to our current WSE 2016 PDCe)
  2. Migrating the FSMO roles to the new DC
  3. Reinstalling WSE 2016 (without the WSE bits)
  4. Syncing the AD and moving the FSMO roles back
  5. Installing the WSE 2016 bits onto the new PDCe
I'm pretty sure I can do it unassisted, but I'd like to have a reference at easy hand to make sure I don't miss anything. The devil is in the details, as we know.
 
Thanks,

    Hi Jeff,

    That should not be so difficult but you should uninstall the Essentials part from the 'old' WSE server before you demote it. You should also disable any cloud integration on the WSE server before demoting or uninstalling the Essentials role.

    uninstall the Essentials part from the 'old' WSE server

    Hm, interesting. I didn't realize that that was even possible.

    It sounds as though you approve of the approach I've outlined, so that helps. And I see here how to do it.

    But could you explain why it should be uninstalled? That VM and its VHDX are going to be deleted immediately after demotion, so I'd expect that it wouldn't matter.

    I am wondering what you are trying to do? Do you need to fix an issue at the current WSE server? Where is the 2022 DC going when you are done?

    You are replicating the AD if you introduce another DC (the 2022) and because of that you must remove the Essentials Experience stuff as it is bound to parts of the AD. The same is valid for the CA, you must uninstall that before you remove the Essentials Experience role.

    I need to rename our WSE 2016 PDCe, as we're inserting a Hyper-V replica server into the mix and we would like to maintain our incremental naming conventions.

    Actually, come to think of it... after the domain leave I could just rename it, rejoin the domain, promote it and migrate the FSMO roles. I shouldn't need to reinstall at all. Everything's healthy—why throw away all that work?

    Wouldn't you agree?

    Where is the 2022 DC going when you are done?

    It'll stay in place as a failover AD/DNS server.

    OK, no I do not agree. I would do a fresh install of the WSE.

    Removing the Essentials Experience role is done from Servermanager Remove Roles and Features. It is a two step procedure. Step one is to remove the Essentials Configuration (see screenshots) and after the server has been rebooted you can go back in Remove Roles to remove the Essentials Experience Role completely.

    This looks good, thank you.

    So I assume that installing the WSE bits after I've installed the server, joined the domain, promoted it and migrated the FSMO roles is done in reverse of the above, via Server Manager Roles and Features?

    Yes, that should work and if it does not send me a note and I will help.
