Appian 18.3 to 18.2 downgrade

We've done this by modifying the xml files in application export to comment out v18 specific "code". I would imagine that you could create script to do the same.

Thanks! and how do you know wich is the specific code in 18.3 not valid in 18.2?

you can check the 18.3 release notes to see if there are any new/changed/evolved functions. If you are using them, you may need to modify.

when you attempt to import, the import will fail because of missing "components"...find those in the XML and comment them out...for instance if it can't import because function "a!whatEver" doesn't exist, find all instance of "a!whatEver" and comment that entire function out...once you import, you will have to replace "a!whatEver" with a function from 18.2 to replace that functionality...note: if "a!whatEver" is in SAIL, you can just put SAIL comments around it to see that was commented out "/* a!whatEver(blah, blah, blah...)*/"
