Previously I setup an Armory online/offline/cold/paper bitcoin storage system. Recently I decided to migrate my bitcoin from Armory wallet cold storage to the BIP39 and related standards. I hadn't switched on the offline PC in a long time, and neither had I updated the blockchain on the online PC. Thus, I started considering my recovery options should something have broken or gone missing. Below are some of the ways I found to recover and move bitcoin in such failure scenarios.
