Migration of CPANEL 10.8 to Plesk 8.1.0

[evolve1]

When trying to migrate CPANEL 10.8 to Plesk 8.1.0 -- The following occurs AFTER clicking NEXT once the IP addresses have been selected:

ERROR: PleskFatalException
Up LevelUp Level
Unable execute MigrationWait::make(): Unable to create bar: assigned values not like "minimal value <= current value <= maximal value (!= 0)

0: /usr/local/psa/admin/plib/common_func.php3:153
psaerror(string 'Unable execute MigrationWait::make(): Unable to create bar: assigned values not like "minimal value <= current value <= maximal value (!= 0)')
1: /usr/local/psa/admin/plib/PMM/MigrationWait.php:282
MigrationWait->make()
2: /usr/local/psa/admin/htdocs/server/PMM/main.php:25



Any ideas on whats going on here?
