Account Addresses after moving wallet.dat to new computer
For this transaction it's 12mjN8ZX8nLNLw9KqTEWoR32J1hsKptEh5 that is the change address.

When you transfer from core it creates a new change address to recieve the balance.

If you do listtransactions you can see them all. listreceivedbyaccount may also be helpful.

Something that is helpful to keep in mind when looking at transactions is there there is no from address, something that sites like blockchain.info show and can be confusing.
