You can always use CRTSRVPGM...In fact I recommend doing so as some of the meta data in the *SRVPGM object is not updated when UPDSRVPGM is used.

The only real advantage to UPSRVPGM is when your *SRVPGM consists of multiple modules and your change management process has one or more of the following issues:

  • doesn't keep the *MODULE objects around.
  • you can't trust the *MODULE objects it finds.
  • doesn't support automated rebuilds of the other *MODULE objects

In those case if you have a *SRVPGM made up of 5 modules, and you need to make a change to a single procedure in one of the modules. You can make the change, then use CRTxxxMOD and UPDSRVPGM to update that single module inside the existing service program.
