Can I keep my discount if I switch from Quickbooks Online Simple Start to Quickbooks Online Essentials...and then back to Quickbooks Online Simple Start?

I currently have a year at 40% off after migrating from GoDaddy Bookkeeping when it shuttered, and I don't want to lose that discount. When I migrated, I migrated too much data--over 54,000 transactions, and I'd like to purge my data, but can't unless I upgrade to Essentials. GoDaddy says it's in Quickbook's hands at this point and says I can't restart the migration there to a new account.

Any suggestions?
