1. Check Requirements
Before you start in-place upgrading, make sure you meet the following requirements.
Requirements for Linux Systems
Before upgrading Plesk for Linux, back up your server data and make sure that the following requirements are met:
- The disk space allocated to the
/tmpdirectory exceeds 100 megabytes.
- A user who runs the installer can execute files in the
/tmpdirectory. This makes it possible to install the system packages required for Plesk.
- If you run Debian, CloudLinux, or Ubuntu, add updates and security repositories to your
aptpackage manager configuration.
Requirements for Windows Systems
Before upgrading Plesk for Windows, back up your server data and make sure that the following requirements are met:
- If you plan to use Microsoft SQL Server support in Plesk, the SQL Server should be installed and configured to use standard or mixed security mode. If the SQL Server is not installed, you can select it to be installed with the Plesk upgrade and configured with administrator name 'sa' and a random password.
