To eliminate unnecessary connection problems, make sure that
The source and destination servers have enough available server and workstation licenses to do the migration.
The eDirectory™ user that you are using to do the migration has no concurrent connection limitations. To check this, do the following:
Run ConsoleOne® on the workstation.
Edit the properties of the User object.
Click the Login Restrictions tab.
Deselect the Limit Concurrent Connections option.
The eDirectory user that you are using to do the migration has the Supervisor right to the source server's eDirectory object. Use ConsoleOne to verify that the User object is listed in the source server’s Operators list.
