In Plesk Onyx we are ceasing support for the components and operating systems detailed below. This list expands on the reasons behind each cease and suggests steps for affected customers.
Customer and Business Manager
Customer and Business Manager is now owned, maintained and supported by Odin (subsidiary of Ingram Micro), so we are removing it from Plesk Onyx distribution. As this product belongs to a different entity, we are dropping its support.
New installations of Plesk Onyx do not include CBM as a part of their distribution and are not manageable with CBM. If you have a remote CBM instance used for managing multiple Plesk servers, we cannot guarantee that it will be able to manage Plesk Onyx. If you were using CBM, we recommend switching to a different billing and provisioning system e.g. WHMCS.
Windows VZ Templates
Plesk Onyx will not support installation and upgrade using Windows VZ templates due to extremely low use of Windows VZ templates among Plesk users.
If you were using Windows VZ Templates to install Plesk, we recommend installing and upgrading Plesk using Plesk Installer.
x86-based distributions of operating systems
Plesk Onyx cannot be upgraded to or installed on x86 (x32) versions of OSes supported by Plesk Onyx due to lack of popularity, reduced efficiency and overall usage decline of x86 architecture compared to x64. The x64-based distributions of OSes are required in order to install Plesk Onyx on the following OSes:
Centos 6 / RHEL 6 / CloudLinux 6
Debian 7
Debian 8
Ubuntu 12.04 (note: will be EOLed in April 2017)
Ubuntu 14.04
Ubuntu 16.04
All other OSes supported by Plesk Onyx are x64-based only.
For those who use Plesk on x86 (x32) versions of OSes supported by Plesk Onyx we recommend migrating your Plesk installations to Plesk Onyx installed on x64-based version of the same distribution. You can use our new Plesk Migrator extension for migration. // NOTE: it would be great to have a link to our website where Plesk Migrator is explained and promoted, but I couldn’t find it //
CentOS 5 / RHEL5 / CloudLinux 5
Plesk Onyx cannot be upgraded to or installed on CentOS 5, RHEL 5 and CloudLinux 5 OSes. These OSes are outdated, their share among Plesk server OSes is very low and they soon will be obsolete and unsupported. Also, a lot of new software doesn’t work on these OSes, which prevents us from delivering new features and fixes.
For those who use Plesk on these OSes we recommend migrating to CentOS 7, RHEL 7 and CloudLinux 7 respectively. You can use our new Plesk Migrator extension for migration. // NOTE: it would be great to have a link to our website where Plesk Migrator is explained and promoted, but I couldn’t find it //
Microsoft Windows 2008 (not R2)
Plesk Onyx cannot be upgraded to or installed on Microsoft Windows 2008 OS. It is outdated, its share among Plesk server OSes is very low and it’s difficult to deliver new features and fixes on it.
For those who use Plesk on Windows 2008 we recommend migrating to Microsoft Windows Server 2012 R2. You can use our new Plesk Migrator extension for migration. // NOTE: it would be great to have a link to our website where Plesk Migrator is explained and promoted, but I couldn’t find it //
Note: Microsoft Windows 2008 R2 is still supported by Plesk Onyx.
ASP.NET 1.1
Plesk Onyx does not support ASP.NET 1.1 on Windows platform. This particular version of ASP.NET is EOLed, does not work on newer Windows Server OSes and is barely used on Plesk servers.
Those who are upgrading to Plesk Onyx from previous Plesk versions will still have ASP.NET 1.1 handlers available on their sites. However, ASP.NET 1.1 will be removed after any reconfiguration of these sites. If this happens, Plesk will switch to ASP.NET 2.0 or 4.0, depending on OS version.
SmarterMail 6.x – 9.x
Plesk Onyx does not support SmarterMail 9.x or earlier. SmarterMail supports only the two latest versions of their mail server software, so they only support SmarterMail 14 and 15 as of the time of this publication. Plesk continues to support SmarterMail 10 and higher.
If you have SmarterMail 9.x or earlier, you won’t be able to manage mail via Plesk when upgrading to Plesk Onyx. We strongly recommend you upgrade SmarterMail to version 10.x at least before upgrading to Plesk Onyx.
Miva
Plesk Onyx does not support Miva scripting. Miva usage among Plesk users is very low and Miva usage overall is steadily declining over the years
If you’re using Miva, your sites and servers using Miva might be able to continue using it after the upgrade to Plesk Onyx, but we do not guarantee their functioning. You will be using Miva at your own risk. We suggest using Plesk 12.5 if you need Miva support in Plesk.
Shared SSL support on Windows
Plesk Onyx does not have Shared SSL feature on Windows platform anymore. This feature was unpopular among Plesk users and with the advent of free Let’s Encrypt SSL/TLS certificates there is no value in it anymore.
If you were using shared SSL on Windows, the shared SSL links will be left in the system during the upgrade to Plesk Onyx. The UI for shared SSL feature will not be available. The domains which used SSL certs provided by another domain will be able to use these SSL certs until the virtual host configuration of these domains is changed. We suggest installing Let’s Encrypt extension for Plesk and using free Let’s Encrypt SSL/TLS certificates to secure your websites.
Unity Mobile
Plesk Onyx does not support Unity Mobile. The Unity Mobile service was shut down some time ago by its authors and it’s not possible to provide it to our customers anymore.
If you were using Unity Mobile, we suggest you find a different solution for creating mobile versions of your websites, if that’s still required.
10.4 upgrade drop
Plesk Onyx does not support direct upgrade from Plesk 10.4 because Plesk 10.4 was EOLed on May 3, 2015. Users of Plesk 10.4 are still able to upgrade to Plesk 12.5.
If you are using Plesk 10.4 and you want to upgrade to Plesk Onyx, Plesk offers free migration assistance from older versions, other panels, legacy solutions or any hosting environment to the latest available Plesk version. The option is available for Plesk commercial license owners and covers the installation of migration tools, environment preparation, fixing/preparing some custom scripts and execution of a single server migration as a test case. With the Free Migration Assistance, migration of the rest of servers is carried out by the owner. Alternatively, you can have Plesk do the job for you by purchasing our Professional Service hours”
