I one of the accounts that I support the Production Environment is the last Environment upgraded. This means that the development environments maybe at higher releases or maintenance than production that means that there maybe an incompatibility between development and production. This requires that what is compiles in our QA environment mirror Production environments. The programs tested in QA are then moved to production and not recompiled. This solves the issue what is tested is what is running in production. The recompile opens up some risk that what is compiled and linked has never been tested.

I trust that before potentially disruptive compiler changes become GA, IBM will have released LE PTFs to accommodate those changes. An 'old library' is not one that has been around for a long time. It's one that has been allowed to molder for lack of TLC. I reiterate that no shop I've been in--every one a business oriented user of vendor products, not a developer--has included recompile as part of SOP migration from test to production. . .
