I believe that you need to upgrade from 5.5 to 5.6 first of all, then do a backup. Use this backup to restore your data on the fresh install of vs7. I have done a couple of these, but went all the way from 5.5 to 5.6, then 5.6 to 6.0, dfone a backup, then restored along the lines discussed in this thread. Had no problems, just time consuming.
