Important
VOSS 8.2 introduced changes to Segmented Management Instance that required migration of legacy management interfaces. Before you upgrade to VOSS 8.2 or later from an earlier release, you must consider your management interface configuration and migration scenario requirements. Backup and save your configuration files off the switch before upgrading to this release.
If the switch already runs VOSS 8.2 or later, you can ignore this section.
Management interface access to the switch can be lost if you do not perform the applicable migration scenarios before upgrading to this release. Loss of management access after an upgrade can result in an automatic roll-back to the previous software version.
You must perform a manual software commit after upgrading from VOSS Release 8.1.5.0 or earlier to VOSS 8.2 or later. Management interface access is required to input the software commit CLI command within 10 minutes after the upgrade. If the time expires the system initiates an automatic roll-back to the previous release.
You must ensure the switch runs VOSS 8.1.x before you upgrade to VOSS 8.2 or later to support the migrate-to-mgmt functionality.
Note
If the network environment must migrate static IPv6 routes, the switches must run VOSS Release 8.1.2.0 or later before you upgrade to VOSS 8.2 or later.
Not all upgrade paths are validated by Extreme Networks for each new software release. To understand the validated upgrade paths, see Validated Upgrade Paths.
You must consider the following legacy management interface migration scenarios before you upgrade to VOSS 8.2 or later:
