Unable to migrate Plesk server 11.5.3

[esbon]

I am attempting to migrate a server with centos 5 to centos 6. Plesk versions are identical on both servers. I did obtain obtain a migration.log file from the source server and it the bottom I find the following error:

[25880]: 17:20:04 DEBUG Exec: /usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/sbin/backup_restore_helper --backup-subscription example.com

The closest solution I found was this: http://kb.parallels.com/en/112964 but I am still unable to migrate

As far as I see this problem is under investigation in Support Ticket #1757727 right now. Please share results here.

The initial issue of the dump file not being able to finish on the source server was resolved. The error was caused by special combination "&" and digit in the string of a scheduled task:
*/30 * * * * wget -q "http://example.com/wp-cron.php?doing_wp_cron&96819510fb05417713a108053cae2775"

The Parallels engineer removed this task as it was suspended and afterwards dump started working.

I did test this by I did running ./PleskX.pl --dump-all inside a test folder I created with instructions from this page: http://kb.parallels.com/1152

Thank you for information.
This can be a great example of how difficult to find the causes of such problems in the frame of forum discussions. Such reasons can be found only with direct access to the server.
