My xxxx-public.sharepoint.com has very limited features compared to my other site collections that are not public. I have spent a while working on the public website but now I need access to features that are not enabled on it. I would like to change it back into a 'normal'site collection. Is there any way I can do this quickly without losing all my hard work? I am not a power-user / coder and dont have access to powe
Their is no OOTB way to convert the Public site into team site as both using the different template.
Now two things you can do.
- Create a team site and move all the content manually
- Use the 3rd party tool to convert it. you can try Sharegate, Metalogix.
