The idf ran in E+8.8 with expected result!s, but when imported to 8.9 the results show an erratic behavior.

What's your graph showing here? Can you show us before and after instead (8.8 v 8.9)? Also, did you check the transition.audit file? Did you use a diffing tool (WinMerge, compare plugin for notepad++, etc) to check differences between the two .idf (=text) files?

Thank you very much for the suggestions. I will check and get back to you soon.

I compared the two IDFs using beyond compare. There were differences related to * Severe * Duplicate name found. name: "CeilingCondFD2". Overwriting existing object. * Severe * Duplicate name found. name: "ExtWallCondFD". Overwriting existing object. Which I resolved by changing the object names

I notice however that when the simulation is launched it does not show warm up loops like it usually does. I have attached an image as an answer below.

That's a known issue - anything with Schedule:File disables the console messages. The simulation runs fine to completion, but there are no progress messages.
