Is there anybody that has used the migration manager in Plesk reloaded 7.5 to migrate from raq4 or raq550 with sucess ?

I`m having problems with it. I get the message "Failed to upload the migration agent.Cannot transfer agent to the remote host
Unable to connect to host 65.xx.xx.xx: you have specified incorrect username or password.

I`v tried both the "root" and the "other" login option, and also the sudo option.

Anybody that has any suggestion about this error ?

Just went through this problem myself and started doing a bunch or reading on plesk. Basically, you need to be able to SSH into the cobalt and login as root instead of admin and then su-ing

To do this, you will need to edit /etc/ssh/sshd_config. There is a line

PermitRootLogin no

You need to change this to

PermitRootLogin yes and then restart sshd --- /etc/rc.d/init.d/sshd restart

I haven't gotten further than this yet, but my plesk server is communicating with my cobalt at this point. Obviously, you need to be able to ssh in from the same subnet that the plesk server is on. If you can't do that, get that fixed on the firewall(s), and then edit the sshd_config
