I have an older wallet.dat file I'm trying to re-open in the latest Bitcoin Core version (0.20.1). Once I replace the empty wallet.dat file with the older one:
Do I need to wait for the entire blockchain to sync before seeing the contents of the wallet? (The point I'm at in downloading the blockchain is well past where the original wallet date was)
If I'm able to see the entire contents of the old wallet before the blockchain is finished syncing can it be done offline or do I need to keep Bitcoin Core online?
