Migration process is seemingly stuck. Process launchpad on destination server is working and consuming CPU resources.


The problem might be caused by SSH server settings ClientAliveInterval and ClientAliveCountMax on the source server. If both of these settings are defined with non-zero values, it may cause SSH server to interrupt connection established by Parallels Migration and Transfer Manager before process of gathering information about source server is complete.


To workaround the problem, either increase values of ClientAliveInterval and ClientAliveCountMax in /etc/ssh/sshd_config on source server, or comment these settings altogether and restart SSH server.
