With this short tutorial we will show you how to upgrade your Plesk 12.5 version to Plesk Onyx.

Before proceeding you should perform a backup of all important data. An upgrade always bears the risk of data loss.

On an SSD VPS you will have the ability to create a snapshot, creating a snapshot will give you the possibility to perform easily a rollback to the state "before upgrading".

On any other VPS or dedicated server we recommend downloading all backup files to your local PC or to our FTP backupspace.

After you have saved all important data you will be able to continue upgrading:


Linux:

1. Login via SSH and use sudo -i to start a shell with "root" privileges
2. Type in the following command:

plesk installer

If this command is not working, you can download and execute the installer using the following commands:

wget http://autoinstall.plesk.com/plesk-installer
chmod +x plesk-installer
./plesk-installer


Windows:

1. Login via RDP and open the CMD.exe with Administrator rights (Windows-Key + R)
2. Type in the following command:

"%plesk_bin%"\ai.exe --console


Once you have opened the Plesk Installer you will probably see a warning telling you to backup all your important files.
