To save the current deployment manager configuration, run the WASPreUpgrade command from the new deployment manager profile bin directory. The WASPreUpgrade command does not make any changes to the Version 7.0 or above configuration.
If you are migrating from Version 8.0 to Version 8.5 and your profile is a deployment manager, Version 8.0 profile is stopped when WASPreUpgrade runs. The deployment manager is started before WASPreUpgrade completes only if you provide -keepDmgrEnabled true on the command line or specify the corresponding option in the Migration wizard.
