Is it possible using two versions of FME Server (2 engines) on the same machine, like FME Desktop?
Out of curiosity, what exactly is the use case?
Have a look here: https://docs.safe.com/fme/html/FME_Server_Documentation/AdminGuide/Upgrade_FME_Engine_Only.htm
Yes you can.
f.e. engine 1 v.2020 and engine 2 v.2021. I've read the link and I think the topic has clarified.
