Deployment & rollout
What does a staged rollout mean?
A staged rollout applies the upgrade in phases instead of all at once. If an early phase fails, the deployment stops automatically and rollback is triggered. This limits the impact of a failure to the phases already completed instead of the entire system.
What are the deployment phases?
A deployment moves through six phases.
| Phase | What's happening |
|---|---|
| Preparing | NimbusWiz is configuring the upgrade environment and staging the upgrade package. |
| Backup & Validation | NimbusWiz is creating a backup and running a final validation check. |
| Executing Upgrade | NimbusWiz is applying the upgrade in phases. |
| Testing & Verification | NimbusWiz is running post-upgrade tests to confirm the upgrade applied correctly. |
| Monitoring | The upgrade has been applied. NimbusWiz is observing the system for stability before marking the deployment complete. |
| Completed | The deployment finished successfully. The system moves to active monitoring. |
How do I roll back a deployment?
While a deployment is in progress, select Roll back deployment in the active deployment section. NimbusWiz starts the rollback immediately. The status changes to Rolling back, then to Rolled back when the rollback completes.
Rollback is only available while a deployment is in progress. Once a deployment reaches Completed, the rollback option is no longer shown. To revert a completed deployment, contact your NimbusWiz administrator.
What gets logged during a deployment?
NimbusWiz writes every deployment action to Audit Logs automatically. No manual logging is required. Logged events include:
- Deployment started.
- Each phase completion.
- Deployment completed or failed.
- Rollback triggered and completed.
Can I run multiple deployments at the same time?
You can have deployments running on different systems at the same time. Only one deployment can be active on a single system at a time.
If you try to start a second deployment on a system that already has one in progress, NimbusWiz shows an error and blocks the new deployment.
My deployment failed mid-rollout. What do I do?
Review the log viewer entry for the failure. If a suggested fix appears in the Suggested Fixes section on the Troubleshooting page, select the action button to open the recommended remediation workflow.
Then re-run the deployment, or roll back if rollback is still available. See Troubleshoot issues.
