I think plaesk support team is busy right now :
we have to discuss our problem and sovle it alone.
Well in my opinion the problem seems to be begin from the source server.
Let's collect logs from database and post it to this thread.
I think for some reason, some sql fields not dumped...
The same here
MU26 installed on both servers.
Destination -> Plesk 11.0.9 ->Centos 6.3 MU #26
Source -> Plesk 11.0.9 ->Centos 6.2 MU #26
