Didn't read the online forums at swsoft.com before thinking to myself that the easiest way to get some domains from my 7.5.4 box to my new fancy 8.0 box was using the Plesk Migrator.

Of course I tried the standard psa_dump/psa_restore, but after a few hours and google later - BACKUPS ARE INCOMPATIBLE BETWEEN VERSIONS!

Well i tried the migrator in my inifinite wisdom.

It managed to remove my RELOAD priviledges from my only MySQL super user account (admin) and half-loaded the domains from my other box (now they are undeletable thx to the mysql errors)

Avoid at all costs!
