How to transfer file shares and DFS?

Question

Windows

There was a need to transfer the domain controller to which the storage is connected via scsi and another storage via iscsi, to another hardware. I rolled the system to a new server, but there were problems with the file server. How to transfer everything?
At the moment, DFS has been raised on the old server, inside which are links to user profiles, a network drive that connects when the machines start, and a couple more folders. Also on the old server there are just balls.
As far as I understand, if you just plug the scsi storage into a new server, then at best it will see these disks, but all the balls will fly off.
I'm also not sure about the name of the computer, if I change the storage, make all the balls back, then I will remove the old domain controller from the domain, and assign its name to the new one, will everything be ok?
readmicrosoft manual on this topic, did not understand anything

1. DFS just allows you to avoid problems, it is also a distributor. The new AD server will be in the same domain, as far as I understand, so we connect it to the same DFS as a mirror .... Although no - it will duplicate everything then. Physically, we have one storage.
DFS is accessed not by the name of the \\server1\files\ server, but by the name of the DFS shares, for example \\domain\dfsshare\files
, which means we raise DFS on the new server, we include the control DFS server (Namespace Servers) as an additional server, on we lower DFS, we check that everything works. Then one fine day / hour we transfer links in DFS to a new location. Everything - DFS migrated.
2. Just drag the balls to DFS, and only then migrate - point 1.
Change the name of the new server that is a domain controller? nope.. not worth it.
There is another temporary option - to refer to the new server by the name of the old one. That is, the dns name oldserver must refer to ip from newserver. At the same time, the old one should definitely be decommissioned, and something needs to be tweaked on the new one so that it accepts connections from clients who call it oldserver.
