Must one know and use code to upload and activate a 2010 SP .wsp file to SharePoint Online? I have a local server housed SP site I created at another location that I'd like to move to my Office365 account. I have created the .wsp file (titled Test.wsp). However, when I upload and try to activate the .wsp file I get
"Sorry, something went wrong This site template doesn't work with the current version of SharePoint."
