After looking through the forums and posing the question to my VAR, it seems to me the general consensus when upgrading to a new release is to NOT run the Conversion Wizard on all SWX files to save them to the newer version.  I would say my leaning is towards converting just the toolbox and then letting users convert files to a new release as needed.  The only item I found on the knowledge base that says otherwise is SWX saying, "Conversion wizard is only supported and intended to convert files from the most recent release to the current one." S-030982.  Has anybody had a problem with older files not converting after a couple of versions have gone by?
