Okay I tried to upgrade to 2.4 from 1.6 by first uninstalling all groupjive components and modules, mambots, and plugins. Then I installed 2.4 but when I tried to view my old groups and categories, nothing was there. I see upgrade instructions for upgrading 1.8 to 2.4 but my 1.6 version is a component not a plugin so how do I upgrade and keep all of my groups and categories?
Here is what I see for 1.8 upgrade:
Uninstall GJ 1.8 CB plugin from CB > Plugin Management if installed
Install GJ 2.4 through CB > Plugin Management
Run GJ 2.4 tools at CB > Plugin Management > CB GroupJive > Tools
Use the Migrate feature present on Tools page to move GJ 1.8 data
Play with and test GJ 2.4 that all working and displaying properly
Uninstall GJ 1.8
