Out of date nodes after Dynamo upgrade

Hi… I tried learning Dynamo a year or two ago and did get some basic results, but my version of Dynamo was updated which resulted in nodes being “Deprecated” etc. so the graph I had painstakingly created no longer worked.
I found this very frustrating but at the same time I appreciated that the nodes were created by third parties who had no obligation to produce them.

So, after getting frustrated with some Revit limitations again I have ended up coming back to try Dynamo and very quickly encountered the same problem…

Can anyone advise exactly how you would go about finding an updated node when you get the “Deprecated” error message ?
It may be obvious to many of you but as a novice, it seems difficult to track these things down.

As a generic example, see the two attached screenshots…

Screenshot1 was created and worked fine.
Screenshot2 is what I get if I open in a newer version of Dynamo.

Thanks
