Notify Users
Inform any users or administrators that the iOS server will be unavailable during the update window. Schedule the maintenance window during periods of low usage if possible.
Review Current Settings and Customizations
Document all current iOS server settings and customizations. You will need to reconfigure these after the update.
Check Dependency Versions
Verify that any software or services relying on the iOS server are compatible with the new iOS version. Update or make plans to update dependencies as needed.
Test the Update Process
If possible, test the update process on a staging server first to identify any issues. Make any needed adjustments to the process before updating production.
Have Rollback Plan Ready
In the event of issues after the update, have a tested rollback plan ready to revert back to the previous working iOS version if needed.
Backing Up the iOS Server
Backups are crucial before any major system update. Make complete backups of:
- iOS server configuration files
- iOS software installation files and licenses
- Any iOS server databases
- Encryption keys or certificates
Test restoring from backups to validate they are working correctly. Offline backups are ideal in case connectivity is lost during the update.
Updating iOS Server Software
With preparation complete, you are ready to update the core iOS server software:
Take iOS Server Offline
Disconnect the server from any live networks to avoid issues during the update process. Disable any monitoring and alerts to ignore status changes.
Install or Mount New iOS Version
Acquire the new iOS version installer or image files. Install or mount the new iOS version according to the vendor’s instructions but do not proceed to configuration yet.
Copy Data and Configuration
Copy over any needed data and configuration from your backups to the new iOS installation. Verify proper permissions on copied files.
Validate Install and Rollback
Do basic validation to ensure the core iOS server components installed correctly. If issues are found, rollback to your previous version before iOS configuration.
Update iOS Server Dependencies
With the base software installed, update any iOS server dependencies like certificates, databases, libraries, etc. to be compatible with the new version.
Configuring the Updated iOS Server
After updating the core iOS components, you need to reconfigure your server:
Review New iOS Version Settings
The new iOS version may include new settings or options. Review and understand key changes before reconfiguring.
Copy Over Previous Configuration
Reference your backup to apply previous configuration settings to the new version where applicable. Some parameters may have changed.
Configure New Required Settings
The update may require new mandatory settings not present in the old iOS version. Consult the documentation and configure as needed.
Integrate with Dependency Versions
Update connection strings, encryption keys, certificates, or other identifiers to integrate the updated iOS server with other updated components.
Run Test Transactions
Perform test operations against the server to validate that connectivity and key functionality work as expected.
Tune Performance as Needed
The new version may perform differently in certain workflows. Monitor performance under load and tune settings like connection pooling as needed.
Finalizing the iOS Update
With the iOS server updated and configured, finalize the update process:
Schedule Post-Update Maintenance
Plan maintenance tasks like old log cleansing or performance optimization for the next maintenance window.
Notify Users and Admins
Inform users and administrators that the iOS server is updated and available again. Notify internal teams to begin testing and validation.
Update Documentation
Update any documentation on the environment to reflect new iOS server version numbers, settings, or instructions.
Monitor Health and Logs
Keep a close eye on server health, logs, and monitoring dashboards for issues related to the update. Have rollback plan ready if needed.
