You can indeed "migrate" VBO to another server and continue without starting from scratch. The only thing you will have "lost" is the password for your account that connects to O365. This is because we are storing that password securely and when you migrate to another computer, you loose one of the keys to decrypt that password. Not a real big deal as you just need to run through the wizard of adding an organization again to add that password in again, and use the new key to encrypt it.
We are also working on a potential migration system so data can be moved between repositories. At this moment I cannot say yet when it will arrive, and we are still studying on different scenario's, but we are intending to give you more options
