FAQ: Can I use my Bitcoin-Qt wallet in Armory?
Unfortunately, Armory does not support the same address format that Bitcoin-Qt uses. The feature was available in Armory until the new format was adopted by Bitcoin-Qt in April 2012. However, Armory will be upgrading its own wallet format very soon, to support wallet types of lots of different programs, in addition to supporting multi-signature transactions (see below). However, even if Armory could use Bitcoin-Qt wallets, they would need to be backed up every couple of months because they are non-deterministic. For this reason, it is recommended that you create a native Armory wallet, and transfer your funds to it instead of waiting for the migration feature (and then make a paper backup of it!). Anything that could be done with a Bitcoin-Qt wallet can be done with an Armory wallet.Also, Armory has a feature that makes it easy to export your private keys, so that they can be imported into another program (such as Bitcoin-Qt). If you try Armory and decide you dont like it, you can use this feature to migrate your Armory wallet to another application. However, for a variety of reasons, it is still recommended to just send the funds to the other wallet instead of migrating
https://bitcoinarmory.com/about/faqs/Is there any way to integrate the private keys and addresses from the old bitcoin-Qt to Amory's deterministic wallet, so that I can just have one neat file without having to constantly backing up the imported private keys? I'm still expecting payments from a lot of these addresses, so I actually do need to import them instead of just generating a new one in Armory.
I also want to import vanity addresses, can these be integrated into the Armory's wallet without having to frequently backup this imported key?
