SharePoint - Best way to convert a SP 2013 (w/attachments) to Document Sets?

Asked By SLM on 13-Jul-21 09:03 PM
I need to convert a SharePoint 2013 list (that has attachments) to a Document Library with Document Sets.

I do not have access to SharePoint Designer and I have limited site permissions which might mean no PowerShell or Flow options (one of the perks of working for the government - sigh). 

I'm only an Intermediate level SP user so I'd need the feedback "dumbed-down" a little bit please.  Any assistance would be greatly appreciated... I'm close to giving up!
