How do I know my dog's 'ghosts' are gone and can I transition her back to a reinforced kennel?

Hello, long time no hear (which is good but things have changed so I am back). 6 year old dog aggressive and separation/claustrophobic rescued Akita. Charm to humans. We purchased the aluminium crate about 5 years ago for when we boarded her she would bust of of their crates. It works great as you know.

We have an indoor/outdoor kennel at home which until recently she respected. Bad lighting storm surged our house blew out electronics. She has not been happy in her kennel ever since but it was well constructed. 2 weeks after the storm, we moved to a new state/home etc. Had a kennel built, but she blew out of it in 5 minutes. left her in the garage. destroyed it. typical story. I am getting her crate AKA Alcatraz tomorrow and read your responses to the 24/7 crating with bark collar. I am ready to try it. Question, how do I know her "ghosts" are gone and can I transition her back to a reinforced kennel?
