This is the basic practice to follow in migrating a user account from *.apf-based to database-based file information as stored in the v11 and v12 clients.
To begin with, make sure you leave the user.apf's in the users profiles.
Locate and open the BackupServer.ini file.
Add the following to the BackupServer.ini
ApfMigrator Active = 0
Open a command prompt
Navigate to the NovaBackup xSP installation directory (ex: C:\program files\NovaNet-Web Backup Server\)
Run the APF migration tool (-apfMigration) using the following options
-d User data directory
-a User.apf file path
-u User account name
-c Database connection string
-apfMigration -d "C:\UserData\test" -a "C:\UserData\test\cache.apf" -u "test" -c "This information can be copied from the BackupServer.ini database connection string"
Using this method you will be able to see in the command window when the migration process is completed for the user. account.
When completed, rename the User.apf to User.old to prevent the information from being overwritten in the future.
