I have set up an offline wallet on computer "A". I set up a corresponding watching-only wallet on computer "B". I have signed and broadcast several transactions. But now I wish to safely move the watching-only wallet to a different computer "C". Then delete the watching-only from computer "B".
- Should I import a digital/paper wallet backup of the watching-only wallet? Is this enough to ensure all existing adddresses and BTC are moved?
- Or should I copy the actual .wallet file manually?
Can this proces be repeated without issues?
