I have a very old wallet, created by the first version of bitcoin. Recently I upgraded to a modern version. However, the wallet has no pool entries. I thought the upgrade would create 100 keypool entries?
It will create 100 keypool entries the first time you request a new address or if you turn on coin generation (the mining threads each ask the keypool for an address to create the coinbase transactions).
I don't know what the story is with "wkey".
