Process of transferring data to SAN

This is the first time I used this software and there were things I still don’t understand. I am planning to transfer a client in the hosted environment. I have already done the imaging of the client’s server and converting it to a VM. After doing that, it will be demoted and combined to the domain that we have, which has resulted for the Sentry Install to be hosted. I’d like the idea of starting from scratch by doing a clean installation of this software. As a backup and to meet required space, I’m thinking of the data to be transferred to the Storage Area Network. Is there anyone who could provide me a step-by-step process on how to do the aforementioned task? Thank you.
