Hello, Reken Liu,
when I was talking about creating new sites from the template I was wondering if it worked on different SharePoints in the manner of
creating a template on https://mysp.sharepoint.com and deploy it to https://yoursp.sharepoint.com ? This is the primary aim of my doing.
Secondly, for it fails to create a template from my SharePoint online I cannot tell you exact FeatureIDs, yet, when I created a template from my development on-premise-server the site creation fails, because feature {2acf27a5-f703-4277-9f5d-24d70110b18b WAReports} was not available on it (and some others, too, when I "corrected" the onet.xml which is provided in the WSP)
Thank you very much,
