in this page here... https://support.allegorithmic.com/documentation/display/integrations/Upgrading+2017.x+projectsthe steps tell you to "Delete the Plugins folder" from your project entirely. Not a good idea, since lots of other plugins install themselves into this same folder. I almost deleted it, and I was like wait a minute .. hahaIt should probably instruct people instead to delete the files that were installed instead?
