Upgrading with a Spare Server

If you have a spare server, you can install Parallels Cloud Server 6.0 on this server and then move Containers and virtual machines to the server. This upgrade scenario is supported for the following Parallels products:

• Parallels Server Bare Metal 5.0
• Parallels Server 4 Bare Metal
• Parallels Virtuozzo Containers 4.7 for Linux
• Parallels Virtuozzo Containers 4.6 for Linux
• Parallels Virtuozzo Containers 4.0 for Linux
• OpenVZ

To upgrade to Parallels Cloud Server 6.0 using a spare server, do the following:

1. Prepare for the upgrade using the instructions in Preparing for the Upgrade .
2. Install Parallels Cloud Server 6.0 on the spare server. For detailed information, consult the Parallels Cloud Server 6.0 Installation Guide .
3. Migrate all Containers and virtual machines from the source server to the spare server. For details on migrating Containers and virtual machines, consult the Parallels Cloud Server 6.0 User's Guide .

   Note: You can convert VZFS-based Containers to the new Container-in-an-image-file (ploop) layout while you migrate them to the host running Parallels Cloud Server 6.0. To do this, use the pmigrate --convert-vzfs --online command.

4. If you store the backups of Containers and virtual machines on the source server, copy them to the spare server.
