Upgrade Considerations

Caution: Beginning with SmartZone 6.1, when using three interfaces, the SZ300 and vSZ-H platforms do not support network configuration with the Control, Cluster, and Management interfaces in the same subnet or VLAN. As a workaround, separate the controller Control, Cluster, and Management interfaces to different subnets or VLANs before upgrading.

Note: Effective December 31, 2024, the SmartZone 300 physical appliance and the associated accessories are no longer supported. You can provision a virtual machine and deploy the Virtual SmartZone (vSZ) software.

Caution: Data migration is not supported if system upgrades from release 3.6.x. Existing system and network configuration is preserved, but data such as status and statistics, alarms or events, administrator logs, and mesh uplink history is not migrated to the new release. Contact RUCKUS support for concerns or additional clarifications. [SCG-73771]
Caution: SmartZone users upgrading from R6.1.2.0 Patch 3 should be aware that applying this patch restricts the upgrade path to the upcoming release of R7.1.1 and above only. Directly upgrading to R7.0.0 Patch 6 or the upcoming release of R7.1.0 is strongly discouraged, as it may result in the loss of certain functionalities. Refer to the Technical Support Bulletin for details regarding the upgrade limitation - https://support.ruckuswireless.com/technical_support_bulletins/642.
Caution: When the controller meets the following conditions before upgrading:
  • Access & core separation feature is enabled
  • UDI interface exists
  • There are static routes for UDI interface
Then, after upgrading to release 6.1.0, static routes for the UDI interface will be placed in an incorrect routing table so these destinations will not be reachable. [ER-9597]

    Note:

  • Due to change in EAP supplicant timeout from default 12 seconds to 60 seconds (SCG-124967), client fails to get IP when RADIUS proxy switch to secondary server.

    It is recommended to change the Radius Option values in WLAN before upgrading the controller or AP to SZ6.1.

    Following are values recommended under Radius option in WLAN configuration:

    • NAS Request Timeout = 5
    • NAS Max Number of Retries Retry = 6

  • DP Zone Affinity is renamed to DP Group and DP Group is renamed as Internal DP Group. Please refer to the Admin Guide for DP Group details on this feature.
  • It is recommended to upgrade the controller Virtual SmartZone (vSZ) before updating the data plane version because if the data plane version is higher than controller vSZ version then data plane cannot be managed by vSZ platform.

When upgrading vSZ-E/vSZ-H, if the memory/CPU allocation of the current VM instance does not match the lowest resource level of the new VM instance to which the new vSZ-E/vSZ-H version will be installed, you will lose the capacity for APs. On the other hand, if the new VM instance has insufficient hard disk space, a warning message is displayed after you upload the upgrade image, but you will still be able to perform the upgrade.
