Challenge: move QS 11.3 jobs into 8.7 installation and determine if they could run successfully.

1. How is this migration done?

2. Do you know right off the bat what to watch out for? What 11.3 features would not work in 8.7? And if you know the workarounds, what are they?

Thanks in advance.

I for one would just pass on this... challenge. There's never been any amount of "forward compatibility" supported. I'd be surprised if anyone here has actually done something like that so the 'gotchas' would all be unknown and your trip into virgin territory would be a solo one with no recourse to support should things go off the rails.

Anything listed as a "new feature" for any of the post 8.7 releases would have to be removed. Those documents are readily available on the IBM website. You'd have to be thorough and check release contents on all fix-packs as well.

No binary compatibility - everything would have to be recompiled.

Thanks for the great insights, everyone. I'll mark this resolved.

Film yourself importing 8.7 components into 11.3, then replay the film backwards.

That's about the only way.
