How to upgrade content egg pro when new release has come


#1

I am already using content egg pro, done settings for the modules. Today(22-Jul-2018), I was notified by envanto that new update for content egg pro which I downloaded. Now when I want to upgrade the the existing plugin, there was no upgrade option, then I tried to add it as plugin by adding the zip, then noticed it is taking as new installation of the plugin, if so my existing module settings will go.
Instead it should be like a upgrade, so that existing setup is not changed.

Any thoughts, please let me know.
