I am hoping to move my client to Server 2025 from 2011 (having done migrations to 2022 for other clients before) but since 2025 doesn't support any AD before 2016 I am trying to figure out how to do this.
Would it be possible to migrate to a tempdc running 2022 and then redo the part where all the AD roles, DHCP, DNS etc are then moved from the 2022 to the 2025 server?
Has anyone done this before?
Hello Peter,
See Seamless Migration: Upgrading from SBS 2011 to a Virtualized Windows Server 2025 Domain Controller and File Server. In the introduction of that kit there is a migration table that answers your question.
Kind regards Mariëtte
Ah thanks, I hadn't seen you had added the 2025 migration. I have been using the your migration kit for going to 2016 Essentials but installing Server 2022 with the Essentials portion kicked in using the WSEE installer from Office Mavens (https://www.theofficemaven.com/news/installing-windows-server-essentials-experience-on-windows-server-2019).
From the brief view of what is on your website it looks like the kit does what I thought would be necessary but it moves things to using the full MS tool set.
We have already as your kits suggested virtualized the SBS servers and were going to put the 2025 server as a VM.
I may take you up on the promo code offer once I get the go ahead to migrate these servers.
