Mike,
Instead of restoring the entire CBU system, would doing the V7R3 upgrade on the CBU system, then either 23. All user data or restore your subset of files on the CBU system be another option.
Restoring a system to another system, and then changing all the settings, is always ugly.
Your basically running a migration.
On the other side of things, the total restore would also test your backup/recovery process, something none of us do often enough, (lack of resources).

Subject: Replicating a production system to a CBU system
Last time we upgraded hardware it was cheaper to buy a CBU system for disaster recovery than to have a contract with IBM to use one of their DR facilities. When we had that new production hardware and CBU installed we had our Sirius consultant do the initial load of our production system to the CBU. Since then we have installed PTFs on the CBU as we installed them on the production system. We also would restore a subset of files and all application changes on a regular basis. Now we have moved our production system to 7.3 but the CBU is still at 7.1. Still keeping it patched but now its time to get it up to 7.3 also. We want to do a full system save on the production system and restore it to the CBU but know that this will mess up the hardware (mostly COMM lines) configuration, network setup and license codes. Does anyone happen to have a document of all the things we would need to document on the CBU system and then update those settings after we restore the production sys
tem backup? Or if there is an IBM Redbook or manual on doing this
Thanks
Mike Cunningham
