Import a Bitcoin account
Looks like you do just have to backup/transfer the wallet.dat
How do I backup my wallet?
Your wallet.dat is stored in the directory ''%appdata%\Bitcoin'', which is typically:
Windows XP: C:\Documents and Settings\username\Application Data\Bitcoin
Windows Vista: C:\Users\username\AppData\Roaming\Bitcoin
Linux: ~/.bitcoin
You need to make a backup of the wallet after every transaction, as the old backup file will be partially or fully invalid. Wait at least a few seconds after your last transaction before making the backup.
