In December 2020, the CentOS community and Red Hat announced the sunset of CentOS. Red Hat also announced CentOS Stream, a new, upstream development platform for the CentOS community. For more information, see Transforming the development experience within CentOS.
What does this mean for CentOS users?
CentOS 7 and 8 are the final releases of CentOS Linux. The end of support (EOS) dates for CentOS 7 and 8 are as follows:
- CentOS 8 - December 31, 2021
- CentOS 7 - June 30, 2024
If you have workloads that are running on these CentOS versions, you might want to review what options are available to you on Google Cloud and start migrating your workloads.
CentOS 7
As of June 30, 2024, the CentOS 7 operating system no longer receives software updates. For Google Cloud customers running CentOS 7, we recommend that you migrate your workloads to another operating system.
Long Term Support options
For maintaining your existing CentOS 7 systems on Google Cloud, there are long term support options from Google partners that provide secure packages, updates, and security patches to extend the lifetime of your CentOS environments. To receive CentOS technical support for your Google Cloud workloads, we recommend the following option:

CIQ, the exclusive provider of enterprise Rocky Linux for Google Cloud, offers access to a global repository of CentOS 7 packages, security updates, and patches to maintain business continuity and regulated industries compliance. In partnership with Google, CIQ is committed to helping Google Cloud customers by providing promotional discounts for CentOS 7 long term support.
Migration options
You can choose to either migrate your workloads that are running on CentOS to a compatible OS distribution, or you might choose an OS that uses a different system.
To migrate your workloads, complete the following steps:
Decide on whether you want to move to a compatible OS or not.
- For a list of compatible operating systems, see CentOS compatible operating systems.
- For a list of other operating systems that you might consider, see Other operating systems.
To move from CentOS to the new OSes, you have the following options:
- Create a new VM with the new OS and redeploy your workloads. Google recommends using this option.
Migrate your workloads to a new OS using conversion tools. Choose one of the following:
- Use the migration tool that is available from the OS distribution that you want to migrate to. While a few community tools might be available for converting your workloads from CentOS to another distribution, Google Cloud does not provide or support any of these conversion tools.
- Use the
migrate2rockytool provided by CIQ to convert CentOS to Rocky Linux. For instructions on how to use this tool and the supported operating systems, see the Rocky Linux documentation. - Use the
Convert2RHELtool provided by Red Hat to convert CentOS to Red Hat Enterprise Linux. For instructions on how to use this tool and the supported operating systems, see the Convert2RHEL documentation.
Append the relevant OS license strings. For a list of OS license strings on Compute Engine, see Operating systems details. To append the license string, see Append and validate a user license.
