CentOS Linux 7 and 8 have both passed their end-of-life dates, so an existing installation no longer receives ordinary updates from the CentOS Project. There is no single replacement for every workload: choose among CentOS Stream, AlmaLinux, Rocky Linux, Oracle Linux, or Red Hat Enterprise Linux (RHEL) based on whether you need a RHEL development stream, a RHEL-derived distribution, vendor support, and a migration route that fits your exact version.
What changed in CentOS—and what “dropped support” means
On December 8, 2020, CentOS Project community manager Rich Bowen announced that the project would shift its focus from CentOS Linux, a downstream rebuild of RHEL, to CentOS Stream, which tracks just ahead of a current RHEL release. The project did not disappear; CentOS Stream continues, but it occupies a different place in the Enterprise Linux development cycle. Read the CentOS Project announcement.
The relevant end dates have now passed: CentOS Linux 8 reached end of life on December 31, 2021, CentOS Linux 7 on June 30, 2024, and CentOS Stream 8 ended builds on May 31, 2024. Treat CentOS Linux 7 or 8 hosts as unsupported for ordinary project updates, and plan a move rather than assuming CentOS Stream is a like-for-like continuation. The CentOS Project publishes version-specific lifecycle information on its CentOS Linux page and CentOS Stream page.
Which CentOS replacement fits your workload?
Start with the reason you chose CentOS Linux: compatibility with RHEL applications, a particular update cadence, community-driven maintenance, or a need for vendor-backed support. The options differ in development position, lifecycle, support model, and migration path.
#1 Best Overall
- Micro-ATX (9.6"x 9.6")
- Support AMD Ryzen 7000 series Processors
- 4 DIMM slots (2DPC), supports DDR5 ECC/non-ECC UDIMM

| Option | Best fit when | Key distinction | What to verify |
|---|---|---|---|
| CentOS Stream | You want to work with the public RHEL development stream or test changes planned for upcoming RHEL minor releases. | It is upstream of RHEL, not the downstream rebuild CentOS Linux was. | Whether its update flow and timing suit your production, development, or CI workload; its lifecycle for the target version. |
| AlmaLinux | You want a RHEL-derived distribution and a project-provided migration route. | It is a separate distribution project, not CentOS Linux under a new name. | Target-version lifecycle, architecture and application support, vendor certifications, and the exact migration guide for your source version. |
| Rocky Linux | You want another RHEL-derived distribution and its published lifecycle fits your planning horizon. | It is a separate distribution project; its support dates are version-specific. | Application and hardware certifications, support arrangements, and the suitability and risks of any migration tool. |
| Oracle Linux | Your application, hardware, or support requirements make Oracle’s distribution a viable target. | It is another RHEL-derived option, but technical relation alone does not establish a fit. | Vendor support requirements, kernel and application compatibility, and the documented source-to-target route. |
| RHEL | Certification, paid vendor support, or a Red Hat-supported conversion path is a priority. | It is the commercial platform underlying the ecosystem, with subscription and support terms to assess. | Eligibility and compatibility for the exact source and target versions, architecture, and subscription. |
CentOS Stream: choose it for the upstream role
CentOS Stream receives work planned for upcoming RHEL minor releases as it is ready, rather than in the former CentOS Linux pattern of batches aligned to RHEL point releases. That makes it relevant for contributors, development teams, and CI that need to test what is coming to RHEL. It may not meet a workload’s requirement for the last or current RHEL release: the CentOS FAQ describes that CI concern as a specific use case, not a universal recommendation. The project lists CentOS Stream 9’s expected end of life as May 31, 2027; check the current CentOS Stream lifecycle information when selecting a version.
AlmaLinux and Rocky Linux: compare the requirements, not the labels
Both are plausible RHEL-derived directions when you do not want CentOS Stream’s upstream position. The available lifecycle and migration information does not establish a general winner. Compare the support lifecycle for the exact major release, certified applications and hardware, project or vendor support arrangements, architecture coverage, and the route from your installed version.

Rocky Linux’s published lifecycle table lists Rocky Linux 9 active support through May 31, 2027, with end of life on May 31, 2032. Those dates apply to Rocky Linux 9, not every Rocky release; consult the Rocky Linux version lifecycle table before committing to a deployment horizon.
Oracle Linux and RHEL: account for support ownership
Oracle Linux can be considered where its kernel, application compatibility, and support model align with your environment. RHEL is worth evaluating when Red Hat certification, support ownership, or a documented Red Hat conversion route matters. Red Hat documents Convert2RHEL paths from CentOS Linux, AlmaLinux, Oracle Linux, and Rocky Linux, but the route depends on the source and target versions and architecture. Its documentation notes that CentOS Linux 8’s last release was 8.5, so the documented route does not support direct conversion from it to the latest RHEL 8 minor release. Review Red Hat’s Convert2RHEL documentation for the exact path.

How to decide: a practical selection checklist
Before choosing a distribution, answer these questions for each important application and host group:
- Position in the release cycle: Do you need an upstream development stream, or a RHEL-derived system intended to follow a released major version?
- Application and hardware support: Confirm that vendors certify the target distribution, release, architecture, and kernel combination you plan to use.
- Update and lifecycle policy: Check the target major version’s maintenance dates and how updates are delivered. Do not infer a release’s remaining life from another version’s dates.
- Support model: Decide whether community documentation is sufficient or whether your organization needs a paid vendor relationship, contractual support, or a specific certification.
- Migration feasibility: Identify a documented path for the installed major version. A tool’s ability to convert some systems does not mean every source-to-target jump is supported.
- Operational risk: Compare an in-place conversion with a fresh installation and application redeployment. Include testing, downtime or cutover constraints, and rollback requirements in the decision.
Can you upgrade CentOS 7 or 8 in place?
Sometimes a documented conversion or staged major-version migration is possible, but there is no universal direct upgrade. Red Hat’s Convert2RHEL utility assesses and converts supported RPM-based systems while retaining configurations and customizations; its documentation distinguishes supported from unsupported paths and asks administrators to analyze the host before conversion. That is not a promise of zero downtime or risk-free migration. Use the exact source-version, target-version, and architecture guidance in the Red Hat conversion guide.

AlmaLinux’s ELevate project uses Leapp and migration data for in-place major-version upgrades among RHEL derivatives. Its guide describes a staged route from CentOS 7 to AlmaLinux 10; it is not a single direct major-version jump. Follow the current ELevate project guide, check repository support for the source host, and review the pre-upgrade report before proceeding.
Prepare before converting or reinstalling
- Inventory the host: Record installed packages, enabled third-party repositories, custom services, kernel modules, architecture, and application dependencies.
- Check support: Confirm target OS, kernel, and hardware support with application vendors and infrastructure providers.
- Choose a route: Match the current major version to a documented conversion path, or plan a fresh installation and application redeployment if that better fits the workload.
- Rehearse in staging: Test the conversion or installation with representative data and integrations; inspect tool reports and resolve blockers before production.
- Protect recovery: Verify backups and test restore procedures. Define rollback or cutover steps and an acceptable maintenance window.
- Execute and validate: After migration, check service health, application behavior, repositories, security updates, monitoring, and backup jobs.
Major-version migration tools can cause data loss; Rocky Linux explicitly warns about this risk in its migration documentation. A tested backup and recovery plan is therefore part of the migration, not an optional extra.
