Funds still showing in old Armory wallet/address after being sent+confirmed to new Electrum one?
It's not Armory that hasn't caught up, but your bitcoind that hasn't caught up. Armory works on top of bitcoind and gets all the block information from the local bitcoind node. It looks like the bitcoind node has about 50,000 blocks to catch up before Armory will notice that the bitcoin is gone. Just let bitcoind catch up (how long will depend on your network bandwidth and your computer's RAM/CPU) and you'll see it once the blocks catch up.
