Upgrade Cluster Image
The Upgrade Cluster Image feature allows Organization Admins to upgrade the ACOS software image on multi-node cluster and entire VCS clusters. It ensures a smooth and automated process with:
- Pre and post-check validation support
- Scheduling options for planned upgrades
- Rollback visibility through workflow logs
| NOTE: | Cluster upgrade is supported for multi-node clusters and VCS cluster, and not for Scaleout clusters. Use the workflow logs to troubleshoot the failures. |
