Exchange 2003 and Exchange 2010 - databases do not see each other

I also checked the log files and this is one of the error messages that I received:
Failed to mount database 'Mailbox Database 0296088125' on test-exwin2010.win.emwd.dst.ca.us (Duration=00:00:00.6327762, ErrorMessage=An Active Manager operation failed with a transient error.

The following appeared a few minutes later.
Finished automounting due to store start (Node=test-exwin2010.win.emwd.dst.ca.us, AttemptedMounts=2, AttemptedDismounts=0, AttemptedDbSyncs=0).

Also after that I received the following messages:
Mount for database 'Public Folder Database 1311307111' finished. (Duration StoreMount=00:00:03.3687625, Duration PreMount=00:00:00.0112008)

ExSearch Mount for database guid=9f480f66-529c-42ab-ab78-3d5022da14a3 on server 'TEST-EXWIN2010' succeeded.

Finished automounting due to store start (Node=test-exwin2010.win.emwd.dst.ca.us, AttemptedMounts=2, AttemptedDismounts=0, AttemptedDbSyncs=0).

Active manager on this server is running as Standalone for duration 02:59:59.6114810 (AuthoritativeServer=test-exwin2010.win.emwd.dst.ca.us, ChangeFlags='None', LastError='<Null>', ServersInMaintenance='')

I was even able to create a new user on the new Exchange 2010 server and then send and receive emails from that user to users on the other server.  My problem is that when I try to migrate users, it shows the name of the server but not the database, so I can't complete that task.

I ran the "Collect Organizational Health Data" and this is the output:
