Cluster upgrades are fundamental to the operations and maintenance of enterprise virtualization platforms, as they are essential for maintaining platform reliability, peak performance, bolstering security, and driving continuous innovation. Yet, the traditional upgrade process is often a liability, requiring frequent, complex, and error-prone manual intervention that is both resource-intensive and risky. Arcfra addresses this head-on with the introduction of the Upgrade Center within the Arcfra Enterprise Cloud Platform (AECP). By leveraging cutting-edge visualization, automation, and fine-grained control, this tool dramatically streamlines upgrades while ensuring unparalleled stability.
Why Does Arcfra Upgrade Center Matter to Your IT O&M?
As Arcfra Cloud Operating System (ACOS) clusters grow in scale and versions iterate more frequently, the limitations of traditional upgrade methods become increasingly apparent. Administrators have to manually verify version compatibility between clusters and Arcfra Operation Center (AOC), check upgrade conditions such as resource usage and kernel versions for each cluster, and manually handle VM migration, kernel upgrades, and maintenance mode switching — all of which make cluster upgrades time-consuming, error-prone, and heavily dependent on human effort.
- Invisible status: It’s hard to directly verify whether upgrade or patch files are compatible with cluster versions, CPU architectures, or operating systems. Administrators must log into each host to check details or manually terminate tasks when issues arise.
- Fragmented operations: The upgrade process is highly fragmented — uploading files, checking environments, updating kernels, migrating VMs, and switching maintenance modes — all handled separately, which easily leads to errors in large-scale environments.
- Uncontrollable risks: Without a pre-check mechanism, teams may not discover the unsatisfied upgrade conditions until the upgrade window, delaying the upgrade process.
- Heavy human efforts: Each cluster upgrade requires constant supervision, and in multi-cluster scenarios, manpower costs double, making it difficult to meet business demands for rapid iteration.
This is where Arcfra Upgrade Center comes in — by integrating the entire upgrade process into a unified management on AOC interface, it replaces repetitive manual operations with automated operations, making cluster upgrades a standardized, traceable, and efficient process.

How Does Arcfra Upgrade Center Enhance Enterprise O&M Efficiency and Independency?
Customer Story 1: From Fully Manual to Fully Automated — Multi-Cluster Kernel Upgrades Now Take Hours Instead of Days
Company A needed to upgrade the kernels of six ACOS clusters. Traditionally, this would require 24 hours and six rounds of repetitive steps, as each cluster had to be upgraded separately due to the high risk of parallel operations. With Arcfra Upgrade Center, the entire process was reduced to just three clicks — and fully automated from start to finish. All six clusters could now be upgraded in parallel within four hours, with zero risk of human error.
| Traditional Process | With Arcfra Upgrade Center |
| 1️⃣ Manually confirm that all clusters and hosts are healthy, with no ongoing data recovery. | 1️⃣ Select target clusters in the Upgrade Center, view details, and verify upgrade files. 2️⃣ Click to automatically run environment checks. |
| 2️⃣ Manually migrate VMs from one host to another. | 3️⃣ Choose the strategy “Upgrade kernel after cluster upgrade.” The system automatically migrates VMs to nodes with lower workloads and sufficient resources. |
| 3️⃣ Log in to each host via command-line to switch to maintenance mode. | The system automatically puts hosts into maintenance mode. |
| 4️⃣ Manually run kernel update commands and reboot the host. | The kernel is automatically upgraded and activated under maintenance mode. |
| 5️⃣ After rebooting the host, verify services, then log in again to exit maintenance mode. | Once the upgrade is done, the host automatically exits maintenance mode. |
| 6️⃣ Manually migrate VMs back to the original host (requires checking VM list) | The system automatically restores VMs based on preset policies—either immediately or after manual confirmation. |
| 7️⃣ Repeat all steps for remaining hosts. | The system automatically performs the same upgrade process on all remaining hosts. During the process, administrators can monitor VM migration status in real time through the interface, and once the upgrade is complete, the system automatically verifies that all VMs have been restored to their original state. |
Customer Story 2: From “Waiting for Support” to “Self-Control” — A Company Independently Completed a Security Patch Upgrade in Just 40 Minutes
When it comes to version upgrades or patch fixes, many IT teams assume such tasks require on-site assistance from vendor engineers or certified partners — time-consuming and schedule-dependent. But with Arcfra Upgrade Center, Company B broke that norm — its IT team independently completed a security patch upgrade in just 40 minutes, making the whole process efficient, safe, and fully under control.
Background: A sudden security patch requirement with tight deadlines
The company’s production systems run on ACOS clusters, which host core business applications and data. During regular maintenance, the IT team discovered a potential security issue that could occur under specific versions. Arcfra promptly released a corresponding Hotfix Package, and the customer needed to apply it within 24 hours to avoid delaying a new business rollout.
In the traditional workflow, the patching process would involve submitting a support ticket, waiting for vendor scheduling, and then relying on vendor engineers for remote or on-site execution. After reviewing the “Install Patch File” section in the Arcfra Upgrade Center user guide, Company B found the patching process with Acura Upgrade Center was straightforward enough to handle internally, allowing them to resolve the issue much faster.
Action: Achieving a simple, efficient, and independent upgrade within 40 minutes
Given the visualized and guided workflow in the Upgrade Center, the IT team completed the entire process — from preparation to installation — in just 40 minutes, with complete confidence in control and safety.
Step 1: Accurate patch matching to eliminate operational barriers
Through the “Upload Patch File” tab, the team simply dragged and dropped the local patch file into the interface — a visual workflow that replaces the traditional command-line input. The system automatically verified compatibility with the cluster’s version and CPU architecture, ensuring no mismatch or human error.
Step 2: Pre-checking the environment to eliminate potential risks
Before applying the patch, the team clicked “Check Environment.” The Upgrade Center then ran a comprehensive system health scan — checking host status, network connectivity, component dependencies, and even prohibited actions like manual maintenance mode switching — ensuring the patch could be safely applied.
Step 3: Full visibility with automated risk prevention
During installation, the interface displayed real-time progress of the patch deployment. The system automatically blocked any risky operations — such as adding or removing hosts or manually rebooting nodes — to keep the cluster stable throughout the upgrade.
