Issue
We are getting the following error in the migration log. Even though we can see this ntf file in the data directory and this is a single user Notes install, and all applications are US versions.

Solution
There is some sort of corruption with your Notes install. We have found that copying the 'btmail.box' file from the Migration Control Center(MCC) and replacing the Data directory on the migration worker(s) resolves the issue.
Or you can create a new btmail.box from the Lotus Notes create new database menu.
