Migrate from classic (v2) to modern (v3) backups

This article will guide you to upgrade from the legacy backup system to modern backups.

Overview

Once migrated to the new modern (v3) platform, you will need to perform a backup upgrade if you were using the the classic (v2) platform if you were using backup system.

If you were not using the v2 backup system we recommend you implement modern backups via: https://knowledge.mycloudit.com/creating-backups

The modern backup system provides many advantages over the classic one including full image based backups (v2 files only), efficient restore, more control over retention and not needing to manage server agent installs, among other advantages.  

If you were using classic backups please follow this guide:
