When DBMigrator is in progress all you see is "Please wait...". There's no indication how far it's gotten nor how much farther there is to go. The user can't tell if he needs to wait another 5 minutes or another 5 days, or even if anything is actually happening. Some sort of feedback needs to be shown the user indicating progress is actually being made by the migration process. In addition, when the process is completed, it would be useful to show something like "N records migrated" to indicate success or failure of the migration process. Instead currently when the process is finished the "Please wait..." is removed. The user can only assume the process was successful and how much data was migrated.
