Hi, I currently have a 1-year subscription active for Bitdefender Total Security 2019 (5 devices). This is valid for another 52 days. Bitdefender currently has a sale offer for the next 15 days to purchase the same coverage for Bitdefender Total Security 2020 on sale. If I purchase this, will it overwrite my existing coverage, or will this be activated when my current coverage runs out? I would prefer the latter. Thanks!
