Parallels Virtualization and Automation Software

SYMPTOMS

The following error occurs during Plesk 8.0 backup restoring on Plesk 8.3 using /usr/local/psa/bin/pleskrestore utility:

Node migration-dump does not have attribute dump-version

RESOLUTION

Note, this issue has been fixed in Plesk 8.4. If you cannot upgrade right now you can follow the workaround below.

Backup file should be fixed manually. Open it in text editor ('vi' is preferred, since it does not reformat file or change life-feeds which may corrupt the file) and add 'dump-version="8.3.0"' to 'migration-dump' node line, before editing:

<migration-dump agent-name="PleskX">

after:

<migration-dump agent-name="PleskX" dump-version="8.3.0">

Also, 'Content-Length' of 'dump.xml' chunk should be increased by the number of characters added (in our case 21), before editing:

Content-Length: 12269

after:

Content-Length: 12291

Now try to restore backup again.
