My attempt is to upgrade CMSMS 1.7 to 2.x
The server is running PHP Version 5.6.21 and I follow the instructions at http://docs.cmsmadesimple.org/upgrading/to-cmsms-2.x
Now I have made the backups, all files and databases. My next step is to "Perform all third party module upgrades.".
Any idea how I know what is third party? I have these modules:

For example, this very first "Calendar", I cannot find it at http://dev.cmsmadesimple.org/project/li ... tml&page=2.
Any ideas, suggestions?
All help is welcome
