Keep Your Clusters Current Without the Risk
Kubernetes releases three minor versions per year, and each version reaches end-of-life within 14 months. Falling behind means missing security patches, losing vendor support, and accumulating deprecated APIs that will break during future upgrades. But upgrading production clusters carries real risk—broken workloads, downtime, and unexpected compatibility issues.
Our Kubernetes upgrade services eliminate that risk. We plan, test, and execute upgrades with zero application downtime. From deprecated API migration to control plane and worker node upgrades, every step is validated and backed by rollback procedures. Whether you need to upgrade a single cluster or dozens across EKS, AKS, and GKE, our certified engineers handle it.
With 200+ clusters upgraded across every major platform, Tasrie IT Services has the experience to keep your Kubernetes infrastructure current, secure, and stable.
DIY vs. Professional Upgrades
What changes with expert Kubernetes upgrade services
Professional upgrades eliminate the stress and risk of version management.
DIY Upgrades

- No rollback plan when things go wrong
- Clusters running end-of-life versions
- Hours of maintenance windows
- Add-ons break after upgrade
Professional Upgrades
- Scheduled upgrades with zero-downtime execution
- All API changes identified and fixed pre-upgrade
- Tested rollback procedures for every step
- Always on supported, patched versions
- Rolling upgrades with no downtime
- All add-ons tested for compatibility pre-upgrade
Kubernetes Upgrade Services

Kubernetes Upgrade FAQs
Common questions about our upgrade services
How do you ensure zero downtime during Kubernetes upgrades?
We use rolling upgrade strategies that upgrade nodes one at a time (or in batches), respecting PodDisruptionBudgets to ensure your applications maintain minimum replicas. We pre-validate all changes in a staging environment and have rollback procedures ready for every step.
How far behind on Kubernetes versions can you upgrade?
We handle multi-version upgrades, even from end-of-life versions. Kubernetes supports upgrading one minor version at a time, so for clusters multiple versions behind, we plan a sequential upgrade path. Our Kubernetes consulting team assesses the effort required during the planning phase.
What about deprecated APIs and breaking changes?
Before any upgrade, we scan all manifests, Helm charts, operators, and custom resources for deprecated or removed APIs. We update them to supported versions before upgrading the cluster. Tools like pluto and kubent help us catch every deprecated API reference.
Do you upgrade managed Kubernetes services (EKS, AKS, GKE)?
Yes. We upgrade EKS, AKS, and GKE clusters along with self-managed Kubernetes. Each managed platform has specific upgrade procedures and considerations that our engineers handle.
Can you set up automated upgrade processes for the future?
Yes. After the upgrade, we can implement automated upgrade pipelines using Terraform and CI/CD that automate future upgrades with proper testing gates, making ongoing maintenance simpler and less risky.
