Does a module created during or for the XOOPS version 2.0.6 need to be converted somehow to work with newer version like 2.0.14RC1? How would that be done or where can I get good info on how to do it?

I'm not aware of any document that tells you what needs to be done to convert a module that was designed for an older version of XOOPS to a more recent version.

The best thing to do is to try it on a test site. In my experience there are some minor tweaks that need to be done to update most older modules, of course that depends on the module. Some of the older modules I've found need to be updated with some of the more recent security changes, include header and mainfile in the right place, etc.

It might help to name the module you're looking at in this thread so you can find out if someone else is already using it on a more recent version of Xoops. You might luck out and find that it "works" or will work with minor mods that someone else has already completed.
