Old Templates

I have old templates from Articulate 5 maybe 6.  I realize its really old but I finally decided to upgrade to the latest version.  Now none of my templates work with this version.  Is there a tool or something that will change them from the previous format to this one? If not I will need to return this software as I don't have the time required to rebuild all the old templates I had and to be honest I don't see any great improvements with this version than the one that was many years old.
