Windows 10: active directory remove on old server 2012 R2 New server become master Windows 2019

Hello Team, We are facing an issue on the servers. As of now, both servers are running user profile loads on random servers. So I have GC/infrsture master/pid/site active dc configured for the new server. So I can remove AD on the old server 2012 R2 either online or offline. Due to ad migration from the old to the new server, the Multipulf GPO object is already visible on the new server. Give me suggestions for the same.

Convert Windows Server 2012 R2 Evaluation to Windows Server 2012 R2

I have purchased the product key of Windows Server 2012 R2. Now the server is on Windows Server 2012 R2 Evaluation. I found a few links there they explained on how to convert from Windows Server 2012 R2 Evaluation to Windows Server 2012 R2 with valid product
key. One of the example is this link:

How to activate Windows Server 2012 R2 Evaluation - Nicolas Ignoto, CTP

Is this a correct way to do? If I follow this step, will my data be erased?

I want to avoid formatting/fresh Windows install because there are some software in the server that we do not know how to backup. We just want to get it activated now, backup will be sorted out later.
