Challenges
- Minimizing Migration Impact: Avoiding service disruptions for end-users (administrative staff, educators, etc.).
- Ensuring Data Reliability & Security: Protecting data throughout the migration process.
- Maintaining Virtual Machine Performance: Preserving optimal performance during and after the transition.
Solution Implemented
- Deployment of a Proxmox Hypervisor Cluster: The team installed Proxmox 7.4-3 on the new HP ProLiant server, ensuring high availability and enabling live migration of virtual machines.
- Careful Planning: By coordinating closely with on-site technical staff, migration tasks were scheduled in defined time slots to reduce user impact.
- Gradual Service Transfer: VMs were moved in stages from ESXi to Proxmox, preserving continuous service for critical applications.
Results Achieved
- Enhanced Availability: Key applications remain accessible with virtually no downtime.
- Increased Flexibility: Proxmox’s cluster management simplifies the creation, backup, and restoration of virtual machines.
- Long-Term Scalability: The institution now benefits from an open, robust solution ready to support future projects.
