Some workstations I am in charge of are still on 1803, for hardware compatibility reasons. We have peripheral hardware that will cause a BSOD in 1903 and higher, so we've been holding off upgrading. We currently don't have a WSUS server, but I am planning on spinning one up soon. I'd like to get them upgraded to 1809 in the meantime.
I've tried using an MCT called MCT1809, but it just updates the workstation to 1909.
1.Is there an MCT (or another way) to update these workstations to 1809 without having to do a clean install?
2.When we do get our WSUS up and going, will it be able to pull down past feature updates, not just the most recent?
