You mean from Bitcoin-Qt? You can't do that.

I have a Bitcoin-Qt, I want to go to Armory.

If you have coins in Bitcoin-Qt and want to move to Armory, you'll have to start Armory, let it fully sync, create a wallet (and, preferably, back it up), and then send coins from the Bitcoin-Qt wallet to the Armory wallet.

The main condition is to save the purse address!

If you can export the purse address's private key, you can add the private key to an already existing Armory wallet. Once that's done, Armory will check the blockchain and get the current balance. At this point, you're good to go. Note that this import won't be covered by the paper backup; you'll have to create a digital backup of the wallet once the private key has been added.

If your main concern to switch to Armory is security, you subvert this by (re-)using old addresses. (e.g. was your address/private key safe in QT, or not?)
Beside, never use the same address twice.
