VB365 Upgrade Guide from v7 to v8

I’ve created a migration guide for moving from Veeam Backup for Microsoft 365 version 7 to version 8.  As you know, version 8 introduces a lot of new changes in the technology and architecture - like postgres database, centralized cache, and proxy pools.  This document will walk through the process of upgrading from v7 to v8, and migrating standalone proxies into the new proxy pools.  Be sure to take care around a “next next next” install, as now with Postgres and NATS, that’s additional workload on the VB365 controller.  It’s recommended to separate out the DB server from the VB365 server outside of the smaller deployments.
