Version and installation information
PE version: All supported
OS version: All supported
We don’t support upgrading a major version operating system of an existing PE deployment. Upgrade the operating system with PE requires you to:
- Back up PE on the existing server.
- Build a new server with the upgraded major version OS.
- Restore the PE back up on the new server.
To back up and restore PE, follow the steps in our documentation.
