SOLVED Migration of SCCM to new Server

[brusilva]

Hello everyone, I'm writing this post to ask for a little bit of help.

I currently have a SCCM instalation on a Server 2012 R2 which I want to replace to a 2019 Server.
My question is, based on your experience what's the best way to move 700 clients to the new server? Deploy a new sitecode and migrate the clients to this new sitecode? The current applications / settings are not a problem migrating to the new instance.
However I have BitLocker Keys saved on SCCM, how will this process manage this keys? Does the devices save the key to new server when assigned to it?

I moved my Site Server to a new server (2012 R2 to 2019) about a year ago. The process went pretty smoothly but I did do a lot of research and prep beforehand. I did my Site Server and MP/WSUS server at the same time. Here are some links which helped me:

The one major issue I had post migration was an issue with updates not working. After some research I found the article below and determined the Catalog Version was reset so I needed to make the registry changes mentioned

Good luck
