Replacing *SRVPGM in production

Has anyone come up with a way to replace an "active" service program in
production (with a new version) without getting pointer errors in the
programs that are currently using it?

I'm looking for some method kinda like how the OS moves existing programs to
QRPLOBJ and other programs calling them can still find them.  That doesn't
seem to work with service programs.  Replacing a service program that is
currently "in-use" always seems to cause the calling programs to lose their
way. I assume that is because the pointers are resolved when the calling
program starts up and the replacing service program goes to a new location.
Is there some way to make calling programs continue to point to the old
service program until they end?
