Upgrade from the Web Interface
To upgrade 8.x or 9.x versions of Plesk to the latest version via the web interface, follow the instructions given below.
1. Plesk Sitebuilder 4.5 is not upgraded. Alternatively, the new version of Presence Builder (former Sitebuilder) installs beside the previous one. Hence, you have the opportunity to manage existing sites in Sitebuilder 4.5 and create sites either in Web Presence Builder or in Sitebuilder 4.5. The upgrade of existing sites to the new format is performed manually.
2. If you used Plesk Billing, add the Customer & Business Manager component to the list of components to upgrade.
To upgrade Plesk from the Web interface:
- Download the Plesk Installer utility that suits your operating system from http://installer.plesk.com/plesk-installer (for Linux) or http://autoinstall-win.plesk.com/plesk-installer.exe (for Windows).
- (Only for Linux) Set the execution permission for Plesk Installer.
chmod +x plesk-installer

Forcing integration with Business Manager
If you upgrade Plesk with Business Manager, the components require some time (not more than five minutes) to set up integration after the upgrade is completed. During this period, you may not see Business Manager links in Plesk, Business Manager may require your password to log in, and you may see a message about invalid credentials when logging in.
If you want to force the integration, log in to Business Manager and reconnect Plesk manually. To do this, go to Home, group Sync Statistics, click the corresponding link, select Plesk ID, and click Reconnect.
