Upgrade to SAGE 300 v2020 - duplicate folders

SOLVED

Hello Communiteers,

I had a demo site running SAGE 300 v2019 . I decided to upgrade it to SAGE 300 v2020 following the v2020 upgrade guide .

The install went OK but I noticed that I now have two folders for each folder under /SAGE, as showed below:

folder tree

So, the install process kept the folders of v2019 and added the folders of v2020. 

Also , the licenses screen shows all the licenses for v2019 and v2020.

Is this correct or did I missed any step of  the upgrade/install ? 

Many thanks
