Removing Replication from Windows Servers Correctly

Hi Everyone,

I'm looking at removing replication and namespacing from two servers without losing any data. In addition during this removal I will adding a third server and finally removing the two old servers. So here's the scenario:

Server1: Running Server 2019. 

Server2: Running Server 2012

Server3: Running Server 2021

Server1 is the main server and has all the data on it. It's data is under a folder/share called "data2020"

Server 2 is the secondary server and is replicated to from server 1. Also Server2 can replicate back to server 1.

I want to first stop replication and then remove the namespace called "dataNS"

Once I remove them I will add the third server (Server3), make that the one that holds all the roles and then decommission the other two servers.

At the end I will have 1 server (Server3) and the others will be gone.

Any help will be appreciated.

Thanks

Steve
