CentOS 6 support stops on November 30. Recommendations to users



RedHat, the creators of CentOS operating system, will stop support of version 6 of the OS on November 30, 2020. Developers will no longer fix the vulnerabilities and problems found after this date. Remaining users of CentOS 6 may lose data and their accounts may be compromised.

CentOS 6 lifecycle has lasted for 10 years:

  • The version was released on November 10, 2010.
  • The stage of active product development with the implementation of improvements and new hardware support finished on May 10, 2017.
  • The last stage of the product's life cycle will finish on November 30, 2020. Starting from that date, RedHat will no longer release security updates.

Check the version of the OS you are using. Connect to the server via SSH and enter the command:

cat /etc/*-release

*If you do not have access to the server, please contact your hosting provider to check the OS version and for taking further actions.

If you have CentOS 6 on servers running under VMmanager, DCImanager, IPmanager, DNSmanager, ISPmanager Lite or ISPmanager Business, we offer several solution options.

Continue using licenses with CentOS 6

The panels will continue to work as before, but you will not receive security updates or hotfixes. Any threat will have to be dealt with without technical support, and your business may be at risk. We strongly recommend using the current version of the OS.

Convert to the current version of the OS

*Not suitable for VMmanager 5 OVZ users

In this case, you will need to move the panel to the “clean” server.

Attention: do not update the operating system on the “action” server — this may cause loss of data.

How to move the panel to another server?

  1. Install the current version of the operating system on the new server.
  2. Next, install a trial version of the product and move data from the main server.
  3. Activate the control panel license. Change the license IP address in the client area. Instructions are available in the technical documentation:

ISPmanager Lite;

ISPmanager Business;


VMmanager KVM;




Instructions for VMmanager 5 OVZ users

VMmanager 5 OVZ does not support CentOS 7. Therefore, in order to upgrade the OS, you need to change the virtualization platform to KVM independently, and migrate to VMmanager 6. You will need to have an active license of VMmanager 6.  

Read a detailed comparison of product versions 5 and 6 in our blog.

Attractive terms of upgrade to the new version regardless of virtualization type are available for all users. Find out more through our chat in at the website, or contact our technical support.
