When configuring resource processing with Resource Updating Manager (RUM), AD Processing Wizard, SQL Processing Wizard, Exchange 5.5 and 2000/2003 Processing Wizard or SMS Processing Wizard, and the option "Select Objects to Process Resources" or "Custom Map" is used, not all migrated objects are displayed in the listing.
This occurs if the number of migrated objects exceeds 2000. The default number of displayed objects within a migrated object listing is set to 2000; similar to the same limit in Microsoft Active Directory.
This limit can be increased by modifying the entry ReturnRecordsLimit in the registry subkey:
HKLM\SOFTWARE\Aelita\Migration Manager\CurrentVersion\Active Directory
Note: Before modifying this value, the Migration Manager console should be closed.
