I'm trying to migrate clients from 8.6 to 9.2.2. When using the Migration Manager I receive the following message so I tried to do this by backup and restore. I created a backup on the 8.6 server, transferred it to the 9.2.2 server and converted it. I created a new client with the same credentials. In the backup menu I chose the converted backup, selected the appropriate options and started it. But I only receive a connection timeout/abort (not a plesk message but a simple browser message) Any help?
