Print Device Migration
Must run in User context to migrate the current printers.
    1) Migrate from Old Print Server to New Print Server
        Chose the Same ServerName if you do not wish to perform a migration
    2) Ensure FQDN is used for all new printers mapped

Assumptions
    1) Your migrating print servers share a common prefix
    2) No Local printers are captured, these must be added manually without further script engineering.
    3) DNS cannot be updated as the old server name must continue to be utilized for other services until EOL

    #Running immediately during Active Setup is not effective since the printers do not appear in the profile yet.
