I created a list from a template with content. The template is coming from a Sharepoint 2013 on premise site. I just noticed when searching the list in SPO it is only finding items added since it was created. Is there anyway to make the old content searchable? I've tried reindexing and Allow items from this list to appear in search results is on.

 

Is there a better way to copy over this list from on premise to SPO.  I've tried the SharePoint Migration Tool but it is not copying it over successfully.

What about writing some PS / C# Code that migrates the list data to a brand new list in SPO?
Is there any way to make the existing list searchable?
