Need drawing template help

My company just made the switch from SW2016 to SW2020. When I attempt to open a drawing I made last week, none of the dimensions are there, the title block is empty, and even our logo is missing. How do I use the template I made in 2016 without completely recreating it for 2020? It worked fine for us all these years and we don't need/want any changes with it. Is this a format or template issue?
