Performing a Hitless Upgrade

The steps described in this section assume the following:

You have received the new software image from Extreme Networks, and the image is on either a TFTP server, compact flash card, or USB 2.0 storage device. For more information, see Downloading a New Image.
You are running a version of ExtremeXOS that supports hitless upgrade.
Review the following list to confirm that your system supports hitless upgrade:
- BlackDiamond 8800 series switches—Both MSMs are running at least ExtremeXOS 11.4 and adhere to the minimum level of ExtremeXOS software required for all modules installed in the switch.

Note

Hitless upgrade for network login is not supported when upgrading from an earlier version of ExtremeXOS software to ExtremeXOS 12.1 or later. If a hitless upgrade is required, you must globally disable network login and re-enable it when the upgrade is complete.
