Cwp to cwp migration takes too long

[luislegacwp23]

Hi every one

Im trying to migrate my accounts to the new server, I followed all steps to migrate but is getting too much time in "Start Transfer Backup"
It seems like the migration module is stock, but I dont know where to find why is stock.

Help please

Seems to be a bug in the latest update. But do you have port 2304 (CWP API) open on both sides?
