Dear, we would like to buy this toolkit: https://www.ispconfig.org/add-ons/ispconfig-migration-tool/ because we have few old VPS that we'd like to migrate to a new software. Actually the VPS that must be migrated are "slave" server of a master-slave stack. Basically this slave server, must be substituted by another "slave" server. And we like to migrate the data of the customer from the old to the new one. I remember that in the past the migration tool, does not support slave server migration on the same master-slave stack. Is this still true or not? Thank you.
