Post-upgrade setup includes some steps that may be required after an upgrade:
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.
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:
To install a license key using a license key file:
To install a license key through the command-line interface:
To install a Plesk license key, use the license
utility:
license <--install|-i> <path-to-key-file | activation-code>
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
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:
