I run MS Money 2000 International English perfectly well on Windows 10 Professional ~ but (like you) realise sometime soon my luck may run out.
All of us, I expect, may have problems if future MS Operating systems do not include Internet Explorer and do not allow it to be installed alongside Edge.
A long time ago I looked at Money 2001 and Money 2002 and found I did not like what Microsoft then described as 'progress'.
My advice to you now Fabrizio is to make absolutely sure that you like Money Sunset before you start trying to migrate your existing data.
I have decided to keep an old Compaq Laptop running Windows 98SE and my MS Money 2000, but without internet access, and just accept that all transactions and share prices will have to be entered manually.
