How long does a paid server transfer usually take?

I red in an old post it can take up to 72h and i am not allowed to login to any(!) toon in that time not just the transfered one. Such a long time would be devastating for my raid schedule or missing event goodies so i am thinking how to time it properly. Or is it much faster usually nowadays?

It’s usually within 5-10 minutes for me. You can log in with another toon as far as I can remember, but I think you need to log out and in again to get the updated server transfer.

It takes about 5 mins and you need to log out and back in
