Using multiple Omniverse Isaac Sim versions

Is it possible to have both Omniverse Isaac Sim 2020.2 and 2021.1 running on the same machine? Or do we have to upgrade Omniverse Nucleus which ends of rendering the older version obsolete? I have 2020.2 installed natively (not as a container), if it matters.

Hi, you can have both versions of Isaac Sim installed on the same machine.
However, only one Nucleus version can be installed. Here are the steps to uninstall the old Nucleus. Upgrading to Omniverse 2021 with Launcher - localhost not matching nucleus - #2 by Sheikh_Dawood
Please download and backup your data first.

From version 2021.1.0, Isaac Sim and Nucleus can be installed from the Omniverse Launcher. Using this Launcher, any Omniverse apps can be easily updated and uninstalled.
