migration from cpanel to plesk failure

[shall]

Trying to migrate a half dozen domains from a cPanel server to my Plesk 8.1.1 server.

Plesk Migration Manager is reporting:

=============================================
ERROR: PleskFatalException

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.php3:151
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

=============================================

And the migration process has now run for over 76 hours on both the Plesk AND the (LIVE!) cPanel system.

How do I completely kill the process on the cPanel box and prevent it from starting up again?

Has anyone found a fix for this funky MigrationWait thing?

Thanks!

I dumped the PMM temp folders on both servers, then logged into mysql and emptied the psa.PMM table, and am restarting the server - hopefully this will resolve any trailing problems with the failed PMM migration.
