I want to run idf file created by v8.7 EP-launch in v8.6 EP-launch.
When I tried, I got following error as below.

Severe * IP: IDF line~81 Invalid Number in Numeric Field#1 (Temperature Capacity Multiplier), value={BCD47EEF-0156-4387-9DD3-E01052AC36F0}, in ZONECAPACITANCEMULTIPLIER:RESEARCHSPECIAL * ~~~ ** Possible Invalid Numerics or other problems

Does anyone know there are any way to convert the newer version to backwards?

The only way to take a file and move it to a previous version in EnergyPlus is to open the file with a text editor (such as Notepad++) and edit the file to conform with the changes between the two versions. I would open the Energy+.idd files for both versions in the diff utility (such as WinMerge) that shows how the file changed between the versions and also look at the transition rules that the EnergyPlus development team uses to document changes in input:

https://github.com/NREL/EnergyPlus/bl...

With those resources, it would be possible to modify an IDF file so that it could be opened in a previous version.

It would probably be easier to just start using EnergyPlus 8.7.
