CentOS migration
Move CentOS 7 workloads to a supported platform
We deliver remote in-place migrations with dependency discovery, a controlled maintenance window, validation and a tested rollback path.
Discuss your project →Prepare the in-place migration
CentOS 7 support ended on 30 June 2024. Before changing the host, we record the operating-system version, repositories, installed packages, kernel, drivers, services and external dependencies. Packages unavailable in the target AlmaLinux or Rocky Linux repositories and components that may block automated conversion are reviewed separately. The preparation output is a command plan, success criteria, an estimated maintenance window and a recovery point from which the original state can be restored.
- Package and repository inventory
- Application and integration checks
- Backup and tested rollback plan
- Agreed maintenance window
- Pilot on a clone or representative server
Execute and validate
During the in-place migration we change repositories and system packages using the agreed procedure, reboot within the controlled window and run technical validation. Checks cover service state, networking, storage, logs, backups, monitoring and application scenarios supplied by the system owner. If acceptance criteria are not met, the prepared rollback route is used. A successful operating-system boot alone is not treated as proof that the workload is ready for production.
Server fleets and ongoing support
For a fleet, we migrate one representative node first, refine the runbook and then define controlled waves. Hosts are grouped by role, criticality and dependency profile so that a configuration exception on one system does not become a fleet-wide incident. After cutover we can support update policy, monitoring, backups and lifecycle reviews. The runbook and validation evidence remain available to your engineering team or MSP.
Fit before scope
Is this the right starting point?
Use these criteria for an initial orientation. The final recommendation follows a review of your context, data and constraints.
A good fit when
- Software is restricted, unsupported or creates operational risk
- Data, history and integrations must be preserved
- Process and acceptance owners are available
Resolve this first when
- Only licence procurement is required without dependency analysis
- A target was selected without validating processes and data
- No one owns reconciliation and the cutover decision
A verifiable first stage
What you can use to make the next decision
The exact scope is agreed before work begins. These are typical decision artefacts, not promised business results.
Dependency inventory
Versions, users, processes, data, integrations and critical support dates.
Replacement-wave plan
Target options, sequence, parallel operation, training and rollback path.
Acceptance rules
Reconciliations, control operations and evidence your team will use to approve the result.

Frequently asked questions
Frequently asked questions
Must the server be reinstalled?
Not always. In-place feasibility is confirmed after checking packages, repositories, kernel modules, drivers and application dependencies.
How is rollback handled?
Before change, we create a backup or snapshot supported by your environment and verify the recovery procedure. The exact method follows the hosting platform.
Can a server fleet be migrated in batches?
Yes, after a representative pilot. Hosts are grouped into waves with their own maintenance windows and acceptance criteria.
