[How to upgrade the app without losing the firewall rules?]

Hello everyone,
Do you know how to upgrade the app from Kaspersky total security to Kaspersky plus?
Do I have to uninstall the Kaspersky total security app first with Kavremvr.exe, before installing the new version of Kaspersky plus?
But I wonder by doing so will I lose all the rules entered in the firewall?
Is there any way to upgrade without losing all the firewall rules?
