1. Introduction

This guide describes how to upgrade

  • Virtuozzo 6 to Virtuozzo 7 in both local storage and Virtuozzo Storage scenarios,
  • OpenVZ 7 to Virtuozzo 7.

When upgrading Virtuozzo 6, you can

  1. upgrade Virtuozzo 6 servers by using temporary spare Virtuozzo 6 servers,
  2. migrate VMs and containers from Virtuozzo 6 servers to new Virtuozzo 7 servers,
  3. upgrade Virtuozzo 6 servers in-place if certain requirements are met.

The exact steps to perform differ depending on scenario and are described further in the guide.

Note

  1. This guide refers to other Virtuozzo documentation that you will need to complete the upgrade: Virtuozzo 6 User’s Guide, Virtuozzo 6 Upgrade Guide, Virtuozzo 7 Installation Guide.
  2. You can upgrade to Virtuozzo 7 from Virtuozzo 6 and OpenVZ 7 only. If your servers run older virtualization products, you will first need to upgrade them to Virtuozzo 6 or OpenVZ 7, respectively. For instructions, see the Virtuozzo 6 Upgrade Guide or OpenVZ documentation.
