We have had issues with mootools not being very backward compatible and I was wondering if anyone has had any problems with Jquery because we are starting to use it and are now using a newer version for several new tools and I was wondering if it would be ok to get rid of the older version.

A:
jQuery seems to be nicely backward compatible. I have been using it for more than a couple of years now through several versions of the core and have not had issues when upgrading except a few minor ones with some plugins. I would say that the core seems to be fine but if you're using a lot of plugins you might run into some problems (but these are usually easy to fix, or the new core has that functionality built in anyway so you can just drop them).

jQuery is so serious about backwards compatibility that they produce a "backwards compatibility" plugin for each release: http://docs.jquery.com/Release:jQuery_1.2#jQuery_1.1_Compatibility_Plugin. It let people who don't need backwards compatibility save on page weight.
