SymptomsThe 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
ResolutionNote, 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" 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:
Now try to restore backup again.
