Locate your previous wallet.dat in the old ‘stronghands’ data directory
COPY the old wallet.dat to the new datadir
The new chain uses a new datadirectory (SHND on windows and macOS, .SHND on linux).
You can either manually create the folder, or run the new client once to create folder.
Start the new client
The new chain should have balances to match your pre-existing values.
Remove old transactions
You may notice pre-existing transactions from the old wallet still appear grey in your wallet, you can remove these by starting the client with the argument ‘-zapwallettxes’
