Hello GeorgeGab, what do you mean direct upgrade does not work ? Do you try to run a newer version of bitcoin core ?
If i install last version of wallet from this site, it give me a two options: 1. import data, 2. skip import.
If i skip import there is 0 btc balance, so i suppose it can't see my current wallet data. Actually there are different path to data in new wallet version. Old one uses path "AppData\Roaming\Bitcoin" and new one uses "AppData\Local\bitcoin.com".
If I choose import, there are another two options. 1. Import through recovery phraze, 2 import from file.
I have no phraze to recovery as old wallet does not use anything like that.
Import from file also does not work as there must be given password. Old version of wallet backuping data without using any password.
