Migration Fails at the first branch

Aug 21, 2009 at 7:00 PM

Trying to migrate some projects from one server to another. Both are TFS 2008.

Migration runs for a bit then fails with "Unable to pend the Branch action to $/ERMS.Delphi 1.9"

$/ERMS.Delphi 1.9 is the first branch from our main code trunk. The project exists in the target TFS server. 

The main trunk and all branches are listed in the Session mapping.

Here's a relevant block from the tracefile.  Why is it getting a zero changeset ID?

TfsMigrationWindowsServiceHost.exe Information: 0 : Microsoft.TeamFoundation.Migration.Toolkit.VersionControlMigrationException: Unable to pend the Branch action to $/ERMS.Delphi 1.9 ---> Microsoft.TeamFoundation.VersionControl.Client.InvalidVersionSpecException: 0 is not a valid changeset number.  Please specify a number between 1 and 2147483647.
