Why not generate an address in your Armory wallet, open Bitcoin-Qt, and send all your money to your Armory wallet?
Thanks for your reply. My question was whether sending from Bitcoin-Qt can preserve a one-to-one correspondence between my original Bitcoin-Qt addresses and new Armory addresses (which is what I meant by "the funds from each original address would be swept into a corresponding new Armory address holding the identical amount", and "if the original wallet had 100 addresses, then 100 new addresses would be created in the Armory wallet"). For example, if I have 3 addresses in Bitcoin-Qt (B1, B2, B3), I'd like 3 new Armory addresses (A1, A2, A3), with all funds from B1 sent to A1, B2 to A2, B3 to A3. (I actually have closer to 100 addresses to sweep).
My concern is that anything I send from Bitcoin-Qt to a new Armory address might mix funds from multiple addresses in an unpredictable manner. However, is it true that Bitcoin-Qt always draws from 1 address if it can? If so, could my idea of sending in order of decreasing address balance ensure that every new Armory address will receive funds from only a single Bitcoin-Qt address? (By the way, all the source addresses should only have a single key pair, because they were never used to send funds before, so they should have no hidden change addresses).
My understanding is that sweeping the list of private keys for B1, B2, etc. in Armory would do what I want (although I'm not sure whether sweeping multiple keys at once would sweep everything into a single new Armory address, in which case I would have to sweep each key one at a time). However, I see 2 problems:
1) Most of the private keys aren't accepted (apparently since the more recent ones have compressed public keys).
2) I'd like to sweep into an offline wallet, and I don't see how to access the sweep function on the watching-only wallet (and it's also disabled on the offline wallet). Is it currently simply not possible to sweep private keys (even in a supported format) into either a watching-only or offline Armory wallet?
Please let me know if I'm misunderstanding anything above, and I'd appreciate any suggestions.
