I've been trying BM3.9.1 on a new OES system patched up to SP7. I'm probably going back to 3.8 (can't abide iManager)

Will I be better off doing a fresh OES install and patching up as far as SP5 (where my current stable production system is) or can I go as far as using the SP7 overlay I used in testing 3.9.1?

If #2, will the 3.9.1 uninstall have left any 'debris' on the server? I will manually remove any orphaned NDS objects.

Thanks, Si.
