2.0 to 3.0RC2 Migration: User Synchronization Errors

I migrated a 2.0 repository to 3.0RC2. It looks like all of my work items, source files, builds, etc. migrated successfully. However, I'm having a problem with users in 3.0RC2. The users that were migrated from the 2.0 repository show up in the "jazz" application user admin web page, but not in the "jts" user admin web page. The admin user that I created during the 3.0RC2 setup wizard shows up in both.
In the "jazz" user admin web page, when I open a user record for one of the migrated users, I get the following error:

An error response was received from the Jazz Team Server. Status=400. Message: The ContributorHandle with the "" item ID doesn't match any existing ContributorRecords.

I go ahead and try to assign a Developer license to the migrated user, but trying to save results in the following error:

Saving user failed. ID CRJAZ1534E
Could not find item in mapping table: com.ibm.team.repository.common.model.impl.ContributorRecordHandleImpl@2db52db5 (stateId: null, itemId: , origin: , immutable: )
com.ibm.team.repository.common.TeamRepositoryException
...followed by the usual ton of unintelligible (at least to me) java errors.

Any idea how to get the "jazz" and "jts" user records synchronized?

Thanks in advance...

You need to run through few migration commands to create the users in the JTS repository. See https://jazz.net/wiki/bin/view/Main/RTCtoCCM30MigrationSteps on the list of migration steps you need to run to create the JTS repository.
