5. Best Practices for Management

• Regular Backups: Even with HD wallets, it is good practice to back up wallet.dat occasionally to preserve metadata (labels and contacts).
• Seed Phrase Supremacy: The wallet.dat file is a technical file; the Seed Phrase (12-24 words) is the human-readable backup. Storing the seed phrase securely renders the wallet.dat file replaceable, but not vice versa.
• Never Edit: wallet.dat is a binary database file. Opening it in a text editor and saving changes will almost certainly corrupt the file and result in permanent loss of funds.
• Descriptors: Modern Bitcoin Core (v22+) is moving toward "Descriptor Wallets." These function slightly differently (storing output script descriptors) and may eventually supersede the legacy wallet.dat structure, though the filename concept remains.

• GUI method: Open Bitcoin Core. It may prompt, "Your wallet needs to be upgraded. Continue?" Click Yes.
• Command-line method:

  bitcoin-qt -upgradewallet
  

  Or, for a specific wallet file:

  bitcoin-qt -wallet=mywallet.dat -upgradewallet
  

Then restart Bitcoin Core with the recovered copy.
