Both of them ensure integration between Microsoft Teams and Confluence and provide similar functionality.
Differences in Lite version:
this app is fully free;
has a limit of 100 Microsoft Teams notification messages sent monthly;

How to migrate the Lite version to Advanced?
There are 3 simple steps:
Start the Free trial of Advanced Microsoft Teams Confluence Connector.
Migrate data from Lite to Advanced on the Global Configuration page.
Uninstall the MicrosoftTeams Confluence Connector Lite, or you will have two versions running in parallel, which will cause you different problems (double menu entries, double notifications etc.).
