Novell ZENworks 10 Configuration Management with Support Pack 1 - 10.1 Migration
Migration Wizard will not go into a particular NDS Organizational Unit (OU) making apps not visible for migration.
This is fixed in version 10.1.3 - see KB 7002526 "ZENworks 10 Configuration Management 10.1.3" which can be found at https://www.novell.com/support
There appears to have been a difference in the attribute order in Directory Services for this one OU that made the Migration Wizard fail. This should be a fairly rare anomaly.
