"Unfortunately, Armory does not support the same address format used by Bitcoin Core. The feature was available in Armory until the new format was adopted by Bitcoin Core 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 Core 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 Core 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 Core). If you try Armory and decide you don’t 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."
