Upgrade from the Web Interface

To upgrade 8.x, 9.x, and 9.5 versions of Parallels Plesk Panel to the latest version via the Web interface, follow the instructions given below.

If you wish to include the Customer & Business Manager (C&BM) component during the upgrade, the Panel host name must be resolvable to an IP address. This limitation is caused by the fact that the Panel uses Single Sign-on (SSO) to interact with C&BM, and the SSO service is unable to work with unresolved host names or directly with IP addresses.

Important: Parallels Plesk Sitebuilder 4.5 is not upgraded. Alternatively, the new version of Sitebuilder installs beside the previous one. Hence, you have the opportunity to manage existing sites in Sitebuilder 4.5 and create new sites either in Sitebuilder 5.0 or in 4.5. The upgrade of existing sites to the new format is performed manually.

Important: If you have bundled Parallels Plesk Billing, add the Customer & Business Manager component to the list of components to upgrade.
