I have an expiring 7-night cat 1-5 at end of July. Can I upgrade it with 30K to the cat 6 to get a one year extension. Then after a couple of weeks (before Aug 1st), downgrade it back to cat 1-5, get my 30K back and have the cat 1-5 certificate with one year extension?
I'm planning on this because I have not read of anyone successfully getting a one year extension on their 7-night cat 1-5 certificates lately.
