After Upgrading Plesk

Post-upgrade setup includes some steps that may be required after an upgrade:

  • Installing a Plesk license key.
    Some Plesk licenses do not grant the permission to perform complex upgrades (upgrades that change a major version number: for example, from 10.3.1 to 10.4.0). On attempt to perform such an upgrade, Plesk will warn you about license limitations. Nevertheless, you will still be able to perform the upgrade. When it is finished, you will need to obtain and install a license key for the new Plesk version.
  • Complete switching to the new business model after upgrading from Plesk 9 or earlier.

    Due to changes in Plesk business model introduced in version 10, if you upgrade from Plesk 9 or earlier, you should perform additional configuration steps to complete the upgrade.

Installing a License Key

Once the upgrade is finished, Plesk may ask you to install a new license key. This may happen with those Plesk license keys that do not grant the permission to perform complex upgrades (upgrades that change the major version number: such as, for example, from 10.3.1 to 10.4.0).

You can install an existing license key either manually from the GUI or remotely from the command-line interface. The latter way is recommended when upgrading multiple Plesk installations.

To get a new license key, proceed to the Plesk online store. Once you purchase the key, you will receive an activation email with your activation code and a license key file. You can install a Plesk license key either by entering the activation code or by uploading the file from this email.

To install a license key using an activation code:

  1. Go to Tools & Settings > License Management > Plesk License Key and click Install Key.
  2. Enter the code you received in the email to the Enter an activation code field and click OK.

To install a license key using a license key file:

  1. Go to Tools & Settings > License Management > Plesk License Key and click Install Key.
  2. Choose Upload a license key file.
  3. Specify the path to the key file you received in the email and click OK.

To install a license key through the command-line interface:

To install a Plesk license key, use the license utility:

license <--install|-i> <em><path-to-key-file | activation-code></em>

For example,

On Linux using a key file:

/usr/local/psa/bin/license -i /tmp/pp11.5key.xml

On Linux using an activation code:

/usr/local/psa/bin/license -i AB1C23-4DEF56-7GHI89-JK1L23-MNP456

On Windows using a key file:

"%plesk_dir%\bin\license.exe" -i "D:\keys\pp11.5key.xml"

On Windows using an activation code:

"%plesk_dir%\bin\license.exe" -i AB1C23-4DEF56-7GHI89-JK1L23-MNP456
 

Configuring Business Manager Connections to Remote Plesk Servers of Earlier Versions

In order to improve Plesk security, in version 11.0, we changed the protocol of interaction between Business Manager and connected Plesk servers. By default, after upgrading to this version, Business Manager continues using the old protocol for interaction with connected Plesk servers of version 10.4 and earlier. To switch the connections between Business Manager and such Plesk servers to the new improved protocol, you should perform the additional configuration steps described below.

To restore the connection between Business Manager 12.5 and a remote Plesk 10.4 or earlier:

  1. Go to Business Setup > All Settings > Hosting Panels.
  2. Find the remote Plesk in Plesk Groups. This Plesk will have a warning icon (warning_icon) near its name. Click Edit.
  3. Re-enter the administrator's password.
  4. Specify the Business Manager IP address - an IP address that Plesk will use to communicate with Business Manager. Usually, this address is the IP address of Business Manager server in its local network. However, the address may be different, for example, if Business Manager communicates with this Plesk through a firewall or a NAT router.
  5. Click OK.
