You can migrate older Virtuozzo 6 virtual machines and containers to Virtuozzo 7 servers. During migration, such VMs and containers will be converted in the Virtuozzo 7 format. In particular, VM devices will be replaced by those supported in Virtuozzo 7 (for a list of VM hardware supported in Virtuozzo 7, see the Virtuozzo 7 User’s Guide).
To migrate a VM or container from Virtuozzo 6 to Virtuozzo 7, run the following command on the Virtuozzo 6 server.
# prlctl migrate <VM_or_CT_name_> root@<VZ7_server_IP_address_or_hostname>
Migration from Virtuozzo 6 to Virtuozzo 7 implies VM and container downtime that depends on network bandwidth, virtual machine RAM size, and server load. To reduce downtime, it is recommended to at least perform migration when the server load is minimal.
