Follow these instructions very carefully. Make sure you backup.
- Start with Bitcoin Core stopped
- Move your wallet.dat file out of the Bitcoin datadir
- Start Bitcoin Core. It should create a new HD wallet
- Get an address from the wallet. Copy it somewhere safe.
- Stop Bitcoin Core. Backup the new wallet file in the Bitcoin datadir
- Move that wallet.dat file out of the datadir to a safe location
- Move your old wallet.dat file back into the datadir
- Start Bitcoin Core
- Send all of your Bitcoin to the address you copied down earlier. Wait for a few confirmations
- Stop Bitcoin Core
- Move your new wallet.dat file back into the datadir
- Start Bitcoin Core. You should see the Bitcoin in your wallet now.
