A few weeks ago I was cleaning up my production PC and noticed I still had Vegas 5 on my system.  I decieded to remove Vegas 5 and i did.  However when I next opened Vegas 6d  shortly thereafer I noticed a number of my effects plugins had disapeared.  then i remembered a thread from long ago warning of that very thing.  Today I tried to search to find an answer but could not locate anything that would help me.
I want to remove Vegas 5 from my PC but retain all the plugins.  Do I need to use the migration tool or what do need to do?
