OK, so this is how I am going about this terribly painful move:
First on oldserver I created two bogus user accounts:
To Be Moved
Already Moved
I then created a matching user account on newserver for To Be Moved.
On oldserver, I change domain ownership of the domains I want to move. So lets say domain1, domain2, domain3.
I then do a client backup from inside of the control panel using the Personal FTP Repository option. I have newserver setup as my repository.
Once the backup is complete and transfered to newserver (if it did not fail) then I access newserver via SSH and do the following:
From the location where I put the backup remotely (and for each domain):
mv *.tar /var/lib/psa/dumps/
cd /var/lib/psa/dumps/
/usr/local/psa/bin/pleskrestore --create-map domain1.tar -map domain1.map
/usr/local/psa/bin/pleskrestore --create-map domain2.tar -map domain2.map
/usr/local/psa/bin/pleskrestore --create-map domain3.tar -map domain3.map
Then once I access the client backup manager in newserver control panel, I can restore the domains. After testing to make sure they work, I transfer ownership to the proper owner on newsever and to Already Moved owner on oldserver.
May not be the best way, but it is working for me and I hope it will help someone else.
Oh, you can transfer the current owner with their domains if they are small. I am in the process of moving my own collection of 80+ domains and hundreds of gigs of data. It would not do it all at once.
