I have an old encrypted QT-wallet with a substantial amount of BTC on it. I also have a new Trezor that is configured and ready to receive funds.

I want to move the funds from my QT-Wallet onto my Trezor without any risk of losing the funds. Thus, I don't want to decrypt it on any computer that is connected to the internet.

My best option as far as I can see is to import the private keys to an offline computer with Armory, then use offline signing to send the funds to my Trezor.

Is this my best option? If so, is there anyone who have some experience with importing keys from a QT-wallet to Armory and could guide me in the right direction?
