We are having WS2008R2/2012R2 DCs, and have upgraded to WS2016 DCs. Now we are planning to move the FSMO roles to new DCs in our root and child domain. Root forest is empty, and child domain has all users/groups/app data.
As we are planning to move all the FSMO roles in both domains (root forest & child domain). I already made plan to first move all the FSMO roles in both env. and then start decommissioning the older DCs first root and then child domain, but manager said first move all the FSMO roles in forest and decommission the older DCs from root, then move moved all FSMO roles in child domain and do decommissioning. I said that their steps are neither advisable nor recommended way to do so, but they are keep insisting on it. If we do so and go by manager's way, it will impact our whole AD infra.
Any article where the FSMO roles movement and decommissioning in this type of environment.
Just wanted to confirm is it the possible way Manager suggested? I don't think so.
Any thoughts on this?
