BUT im pissed that legacy wallets wont be supported from 30 on?? wtf
They aren't supported, but the migration tool is built into the software and will seamlessly (in the vast majority of cases) migrate your legacy wallet into a descriptor wallet.
Do you mean the existing migration tool or the one updated in version 30?
Im also interested in knowing what version my wallet is. I reckon it must have been around 2013, but im not sure what actual current wallet.dat stuff is on the file right now. Is it possible to find out?
