Thanks Brook for the speedy answer. I made sure to have multiple backups first. I misunderstood how Network vs Site Plugins worked. I thought they were installed from either the Network Plugins page or a specific Site’s Plugins page. Plugins are installed the same way, but you can choose to activate it on a single Site or for the whole Network. I didn’t have to reinstall the Plugin or worry about my events getting deleted.
I went to the Network Plugins page, clicked on Network Deactivate on “The Events Calendar” & “The Events Calendar PRO” Plugins. Then I went to the specific Site’s Plugins page and activated “The Events Calendar” & “The Events Calendar PRO” Plugins. My events were all still there.
