Install SC v10.2 with SC v9.13

Can I install SC v10.2 in a new directory named “sc10” on my existing production server (which runs Debian 12, LAMP, MariaDB, and Webmin panel)? Furthermore, can I directly copy all applications which are stored in the current version “sc9/app” folder to “sc10/app” folder from my current projects—which are running on SC v9.13—into this new setup, and use the same license for both versions? This would allow me to manage my legacy applications while also building new ones in v10.2.

Adopting this approach would help minimize errors or bugs on our production server, as we wouldn’t need to constantly upgrade applications to the latest version.

Currently, every time a new version is released, our active projects are affected. We often hesitate to perform upgrades for several days, fearing that it might disrupt our existing, functional applications.

Could you please provide your suggestion on whether this is a recommended approach?
