Can I use Total Security activation code in Internet Security windows application and keep using KIS?

I want to keep using Kaspersky Internet Security program on Windows 10 as long as possible and I don't want to switch to Standard or any of the newer named apps yet. My current activation code for KIS expires in a couple of months.

Where I live I can only find in reliable stores retail versions (with activation code in box or card) the Kaspersky Total Security for 1 or 2 years. I don't need and I don't want the extra things Total Security offers over Internet Security and I don't want to mess my setup. So I want to ask can I use Kaspersky Total Security code to activate my current Kaspersky Internet Security (the latest update of KIS 21.3.10.391 (k) ) app or a new install of KTS Kaspersky Total Security is required? Can I use KTS code as KIS code?

Or else what is the right way to move from KIS to KTS, current articles are not that clear they are say that I can enter the code in KIS and choose when to move to KTS? It will download and and install over it? Will I lose my firewall settings or other settings after that? I really want to avoid a clean install and I don't want KTS extras anyway.

One other thing I want to ask is for how long will Kaspersky Internet Security and Kaspersky Total Security will receive definition updates and required to work on Windows 10 updates? Will a 2 year KTS code will actually work for another 2 years?

If anyone knows about the licensing thing or at least anyone who made the switch from installed KIS to KTS please help me with details, I read all FAQs and articles and they didn't help me. Thanks in advance.

@menachem Welcome.

With a KTS code you can only activate KTS and with a KIS code you can only activate KIS. Both products are not EOL , as far as I know you will receive update definitions during the coming years …
