2 node DFS only replicating one way

Question

I have 2 nodes server A(2012r2) and server B(2022). Server A is an old file server we are replacing and server B will be the new file server. Once users are migrated over to server B we will shut down server A.

I have set up a DFS share between the 2 servers. It appears that all the data from server A is now on server B. If I add a file to server A it is on Server B almost instantly (10GB connection). however, if I add a file to server B it never makes it to sever B. both servers show 0 files backlog.

I am new to DFS and the lack of any good monitoring is a little crazy to me.

what steps should I be taking to troubleshoot this?

The firewall is off on both servers.

I have read so many posts on here but there never seems to be a real answer just manual workarounds or it doesn't apply.
