Firstly, it would seem that both myself and Synthia came up with the same basic premise for conciousness transfer.
clone gets made : tranciever gets installed. Remote access is re-activated.
Z-ARK, for you i'd say it's a lot more simple. Creating a copy of a proven technology is a lot cheaper than researching and prototyping it, so, while your first cyber-body was likely expensive and one-of-a-kind, after it's creation, you could easily have built a whole array of replacement bodies just in case you needed to reclone.
As for the transfer of conciousness and memories, as you are playing a full AI, and instant-communications exist, you could easily have a backup server somewhere that keeps a real-time copy of Z-ARK's memories and experiences, then, when a body goes pop, you simply send the activation code to the next one, and upload the most recent 'save'
As others have mentioned, I have found that the best way to play any AI slanted character, whether it be a full AI like yourself, or an AI augmented human mind like Yuni, is to keep it simple, keep it consistent and to keep specifics regarding your history somewhat vague.
I would also suggest reading up on Asimov's laws of robotics and how they have been used in popular media. I found them useful when building Yuni's character in my head.
