Copying the blockchain to a new computer

[Isanderthul]

I would like to make another node on a new computer, without waiting a long time for the node to sync.
#3185 discusses copying the blockchain

What is the relationship between
~/.chia/mainnet/db/blockchain_v1_mainnet.sqlite
and
~/.chia/mainnet/wallet/db/blockchain_wallet_v1_mainnet_*.sqlite

If I copy ~/.chia/mainnet/db/blockchain_v1_mainnet.sqlite, but not ~/.chia/mainnet/wallet/db/blockchain_wallet_v1_mainnet_*.sqlite, what work does the new node need to do?
