Not just for Enterprise COBOL, but for all languages that use an LE run-time, it is now and has been for as long as I can remember CRITICAL that the run-time on all systems be at the "highest level" *before* you start rolling out object code created by "higher-level" compilers.
This goes all the way back to the old PL/I RESIDENT (or was it TRANSIENT) library. If this means that you keep the "old compiler" - even in your development systems UNTIL LE is upgraded on all production systems, then this is what I would recommend (and I think IBM does). The old "RTLS" support *tried* to provide a solution for this, but having "up-level" LE on all production systems is simply the "way to go" before beginning compiler upgrades.
