Server transfers are still in the same state as they were after they were removed: Nonfunctional
All it would do is delete/corrupt your character data requiring rolling back the server you transferred from to restore it.
You will hear from FC when they fix server transfers so that they work with the current version of the game.
I assume they will be able to get PVE sieges working in Siptah before server transfers.
