How do I upgrade my Adtran vWLAN system to version 4.1.0?

[LilaDella]

Upgrading your Adtran vWLAN system to version 4.1.0 requires a specific upgrade path to ensure a smooth transition. Here's a step-by-step guide to help you succeed:

1. Version Check: Verify your current vWLAN version. You must be running at least version 3.7.1 before proceeding.
2. Pre-Upgrade Patch: Install the 4.1 Pre-Upgrade patch onto your vWLAN system. This patch prepares your system for the final upgrade.
3. Upgrade Path: If your current version is between 2.3.0 and 2.6.1, first upgrade to version 2.6.2. Then, upgrade to version 2.8.0. Next, upgrade to version 3.7.0. Then upgrade to version 3.7.1. Only after completing these steps should you install the 4.1 Pre-Upgrade patch and finally, upgrade to version 4.1.0.
4. BSAP Firmware: Ensure your BSAP (Bluesocket Access Point) firmware is also version 4.1.0 or newer. Adtran vWLAN 4.1.0 is not backward-compatible with older BSAP firmware.
5. Error Handling: If you receive an error message stating you must be on version 2.8.0 to upgrade to 4.1.0, follow the recommended upgrade path outlined above.

For detailed instructions and troubleshooting tips, consult the "Upgrading Bluesocket vWLAN Controllers and APs" guide, available on the Adtran Support Community. Following these steps will help you successfully upgrade your Adtran vWLAN system to version 4.1.0, enabling you to take advantage of the latest features and enhancements.
