VeloCloud SASE Orchestrator Upgrades:
Q: What is the impact of a VeloCloud SASE Orchestrator upgrade?
A: Before the scheduled upgrade, a data transfer is performed on the Orchestrator to prepare for the cutover. On the control plane, there will be intermittent performance degradation during this time. Customer traffic is not affected.
During the upgrade:
- Users will experience a brief loss of access to the Orchestrator.
- Configuration updates to VeloCloud Edges will be disabled.
- Edge and Gateway services are not impacted.
- QoE data may be missing during the upgrade period.
Q: What happens if there are issues with the upgrade?
A: In the event there are issues with the Orchestrator upgrade and Engineering is unable to restore service on the new version, they can restore the
Orchestrator from a backup taken prior to the upgrade.
VeloCloud SD-WAN Gateway Upgrades:
Q: What is the impact of a Gateway upgrade?
A: During the upgrade
- Most customers will not observe any impact.
- The Gateway will be down for no longer than 3 minutes during the cutover to the new version.
- Non SD-WAN Destination (NSD) via Gateway tunnels will go down during the upgrade (for the duration of the cutover). If a redundant NSD is available, traffic will be re-routed via the redundant Gateway.
