Preserve the modern home.aspx page when migrating to a new modern site
I'm having trouble migrating to Modern Sites. I have nearly 1000 site collections/subsite in a SharePoint 2016 farm that I'm migrating to SharePoint Online. However, we're wanting to keep the modern look and feel. No matter what mapping settings and options I try, I cannot accomplish this. The end result is a SharePoint Online site collection that is using the STS#3 template, but looks like SharePoint 2016. The issue appears to take place at the end of the copy content operation when the home.aspx file is copied over to the Site Pages library. Is there any way to change this behavior? I realize copy content would work, but that's not an option with this many sites.
