The new images are based on Ubuntu 24.04 LTS, replacing the previous 22.04 LTS version. +Upgrades will also be faster, as nodes will be replaced instead of rebooted. + + +## Technical specifics of the upgrade Process + +* **Node replacement**: During upgrade, nodes will be replaced with new ones, which may have implications for data stored locally on nodes (e.g., `hostPath`). Data stored in persistent volumes (PV) will not be affected. +* **New IP addresses**: The new replacement nodes will have new IP addresses (both public and private), which could impact IP filtering configurations. +* **GPU pool upgrade**: The upgrade of GPU pools may result in a partial downtime due to a limitation in the GPU operator, which cannot handle mixed Ubuntu versions (22.04 vs 24.04). The operator will install incorrect drivers on new nodes until the upgrade is complete, after which it will recover automatically. + +## Upgrade methods + +You can migrate your Scaleway Kubernetes Kapsule cluster to the new image system using either the console or the CLI: + +### Console upgrade + +1.
