- Plesk 12.5 for Linux
When migrating domains from Plesk 9.x to Plesk 12.x, each domain is created in destination Plesk as a separate subscription and, therefore, the structure of domains' directories is different.
There is no option to transfer domains owned by one customer to the same subscription in destination Plesk 12.x
This is default behavior because of new Plesk business model introduced since Plesk 10.4 . Please, refer to Plesk documentation for more details.
