When I was doing systems programming work of this type, we always installed the exits using USERMOD statements in SMPE. Then if any exit needed re-assembly it would be done automatically by SMPE. It takes a little work to understand the process, but it pays off in the longer run.

However there is no requirement to *always* reassembly an exit when migrating to newer z/OS version. However: 1. Why do we reassemble? Because exit uses macros and structures which are likely (but not always) may change. 2. Instead of detailed analysis which it is simply easier to reassemble. 3. It is not only system upgrade. It can be some PTF as well, which causes the need to reassemble. IMHO much less likely. 4. There are exits for some applications, in that case the need for reassemble would be different. It can be because system change or product change. Or both.
