CentOS 6 EOL is just around the corner, with its due date scheduled for November 30th, 2020. If you have servers running on CentOS 6 systems, make sure to prepare for this occasion.

Learn what to expect after November and how to deal with the transition.

CentOS 6 End of Life

At some point, every Linux release becomes EOL, that is, it reaches its end of life.

Although CentOS releases have exceptionally long life cycles, version 6 reaches its own by the end of November 2020. In comparison, CentOS 7 will be supported until June 2024. Surprisingly, the CentOS 8 life-cycle has been cut short and its EOL has been scheduled for December 2021.

Becoming EOL means it will no longer be supported by the Linux community with security patches, vulnerabilities, or bug fixes. Therefore, continuing to use CentOS 6 after November could pose a significant security risk. That is why it is advisable never to use EOL operating systems.

If you are using CentOS 6 on any of your machines, you have a couple of options available going forward.

Option 1: Migrate to CentOS 7 (Recommended)

An alternative to upgrading to CentOS 7 is migrating to a new system with a freshly installed supported release. Doing so allows you to configure the server to a more recent CentOS version and safely migrate data.

To install a fresh operating system and then do a data migration, refer to How to Install CentOS 7.

Option 2: Upgrade to CentOS 7

The easiest and least costly option is upgrading from CentOS 6 to CentOS 7 from the existing release. However, this solution is not recommended for production servers and it may involve using unofficial custom scripts.

If you do decide to upgrade CentOS, make sure you have a reliable backup as there is always a possibility of data loss with such a transition.

Option 3: Self-Managed Support

If switching to a newer CentOS release isn’t an option, you can continue using the EOL version with self-managed support. Without the support of the Linux community, you (or a hired team of experts) will need to take over managing potential security threats and to fix any known bugs.


Generally, the recommended option is doing a clean install and migrating workloads to the new OS. Still, whatever you choose, make sure to switch to a supported version before CentOS 6 becomes EOL.
