There are four ways to perform Plesk deployment described in this guide: installation, upgrade, transfer, and migration.
Plesk installation can be performed either manually (suits best for single installation) or in an automated, unattended, manner. The latter way is recommended for installing Plesk on multiple servers. For mass Plesk deployments, we also recommend that you install Plesk instances to Virtuozzo.
Learn more in the chapter Installing Plesk.
If you use an earlier Plesk version, you can upgrade it to a later version when it is available. There are two ways of upgrading Plesk: in-place upgrade and upgrade by transfer. While in-place upgrade is the updating of Plesk components within one server, upgrade by transfer implies moving of data from the server with earlier Plesk version (source) to the server with a later Plesk version (destination).
Learn more in the chapter Upgrading Plesk.
Plesk supports transferring hosting data (service plans, subscriptions, and so on) from one Plesk server to another. This allows you, for example, to seamlessly move your Plesk to a more productive server.

Migration is the only way to switch to Plesk from other hosting solutions (CPanel, Confixx, and other). This is done by transferring hosting data from a source server to Plesk.
