Thanks Tim. That was the answer I was hoping for. As for why we've always done FSR: until 2.1, we've been an 'MVS' ESP customer as long as ServerPac has existed. ESP customers have to hit the road several months before GA. In the beginning, ServerPac was not even available to ESP customers. Once it became available, FSR was the only path. So by the time SU became available for ESP customers, our procedures were pretty well entrenched.
We migrate a z/OS image from (non-IPLable) SMP/E environment to 7 running sysplexes. The release-level HLQ is a cornerstone of these processes. I will give SU a shot. . .

Sent by: IBM Mainframe Discussion List <[email protected]> Service upgrade does create a catalog specifically for the install and ongoing maintenance of the zOS release. I think of it as one of the SMP datasets because that is the only thing that needs it. It has an alias for the SMP support datasets (ex. SMP21) and an alias for the target and dlib datasets (ex. ZOS21). DDDEFs point to alias names such as ZOS21.SYS1.LINKLIB ZOS21 is an alias in the driving master cat pointing to the release specific catalog on the SMP volume. The ZOS21.SYS1.LINKLIB dataset alias points to SYS1.LINKLIB on volser Z21RES I used full replace a couple of times in the beginning but found that I didn't need the support datasets. I use Mark Zeldan's one pack JCL to build on a borrowed volume for the IVP IPL. (xcflocal) Then apply usermods and clone a normal RES volume (we rotate 3) and IPL it in the TECH lpar. (multisystem) That way; the serverpack datasets never get IPL'd; we only run from copies.
