Issue
There is a lack of clarity regarding the necessary preparation steps for upgrading a Continuum LAN system. Inadequate planning can lead to compatibility issues, data loss, or system downtime.
Product Line
Andover Continuum
Environment
- Continuum Cyberstation
- SQL Server
Cause
Upgrades without proper preparation may result in:
- Software and hardware incompatibility
- Data integrity risks
- Extended system outages
Resolution
To ensure a successful upgrade, follow these best practices:
1. Review Compatibility Matrices
- Consult the Continuum Compatibility Matrix and Continuum Video Compatibility Matrix.
- Use these tools to plan upgrades for all supporting software and hardware.
2. Verify Software Compatibility
- Ensure that .NET and SQL Server versions are compatible with the target Continuum version before starting the upgrade.
3. Update Controller Firmware
- Older CX controllers (firmware ≤ 1.500029) use a different handle algorithm and must be upgraded prior to the LAN upgrade.
- Other controllers can be upgraded after the front-end systems are updated.
4. Assess Hardware Requirements
- Evaluate all current computer hardware, especially the Continuum Database Server.
- Choose hardware based on customer needs and system requirements.
- This decision should involve engineering expertise and likely the customer’s IT department.
5. Consider Off-Site Preparation
- When deploying a new database server, it may be beneficial to build and prepare the Continuum server and database off-site.
6. Engage Experienced Engineers
- The upgrade process is complex and should be led by an engineer experienced in Continuum LAN upgrades.
- This ensures proper execution and provides mentorship for technicians involved in future upgrades.
