I want to have the wallet version that i used when i mined bitcoin back in 2014. I have a bunch of wallet.dat files but i don't know if i have the one that i used for mining in 2014.
You mean Bitcoin Core version?
Because there should be no issue on restoring the copies of your old wallet.dat files to v28.1.
Use "
Restore" and do not "
Migrate" in this case to keep it in legacy wallet format.
And if you want to export all of its keys, use
dumpwallet command in the console. (
dumpwallet command)
Before using the command, set
addresstype=legacy in your bitcoin.conf file (
requires restart to apply)
If the old wallet.dat in relatively new (
about year2017+), repeat the dumpwallet command after setting:
addresstype=bech32 and once again for
addresstype=p2sh-segwit.
And to look for deleted wallet.dat or private keys, try Pywallet's recover command:
