GEDmatch (www.gedmatch.com) should be accepting new FTDNA (FamilyTreeDNA) uploads soon. Also, they are renumbering and renaming existing FTDNA kit numbers. The below is posted on GEDmatch.
If you plan on making copies, do it now. Also, if you use another site that downloads from GEDmatch (several come to mind), you will most likely need to re-download after the change-over. Check whatever site you are using and see how they advise to handle the change.
