Best practices and recommendations

• Keep a record of device software version and date before upgrading.
• Only install firmware from trusted vendor sources.

• Avoid upgrading if the device works fine and the update does not address issues you experience.
• Keep the firmware file and a backup USB copy in case you need to reapply.

Pre-upgrade Preparation

1. Inventory
   • Record device IDs, current firmware versions, serial numbers, IP addresses, physical locations.
2. Backups
   • Export/save current configuration files for each unit to secure storage (timestamped).
   • Take photos of physical connections and recording of current channel line-up.
3. Firmware Acquisition & Verification
   • Download latest WS-6979 firmware from vendor site or vendor-supplied build.
   • Verify checksum/signature against vendor-provided value.
4. Compatibility & Release Notes
   • Review release notes for breaking changes, required config changes, and supported hardware revisions.
5. Test Unit
   • Designate 1 unit as pilot/test. Schedule upgrade on test unit first.
6. Stakeholder Notification
   • Notify operations, NOC, and any impacted customers of planned window and potential brief outages.

How to find the official software:
