The following sections specify all current TSBs that have been identified as being a risk to or resolved with this specific version of Fabric OS. Please review carefully and refer to the complete TSB for relevant issues prior to migrating to this version of code. TSBs can be found at http://my.brocade.com under the "Technical Documentation" section of the "documentation" tab.

TSB TSB-2012-143-A Summary In Fabric OS v7.0.1 and v7.0.1a, an Integrated Routing license is incorrectly required for VEX_Ports on FR4-18i blades. Recommended Migration Paths to FOS v7.0.2 Migrating from FOS v7.0 Any 8G or 16G platforms running any FOS v7.0.0x or FOS v7.0.1x release can be non-disruptively upgraded to FOS v7.0.2. Migrating from FOS v6.4.x DCX/DCX-4S units running any FOS v6.4.x release can be non-disruptively upgraded to FOS v7.0.2. Any 8G platforms (other than DCX/DCX-4S) that are currently operating at lower than FOS v6.4.1a must be upgraded to FOS v6.4.1a or later before non-disruptively upgrading to FOS v7.0.2 Upgrading these platforms from any FOS V6.4.x release lower than FOS v6.4.1a to FOS v7.0.2 will cause disruption to FC traffic. Upgrading any 8G platform operating at FOS v6.4.1a or later to FOS v7.0.2 is non-disruptive to FC traffic. Migrating from FOS v6.4.1_fcoe1 The upgrade from FOS v6.4.1_fcoe1 to FOS v7.0.2 is non-disruptive to both FC and FCoE traffic on DCX and DCX-4S. Note: Upgrading from FOS v6.4.1_fcoe or FOS v6.4.x releases other than v6.4.1_fcoe1 to FOS v7.0.2 will be disruptive to FCoE traffic going through FCOE10-24 blades in DCX/DCX-4S. When loading FOS v7.0.2 with Brocade Network Advisor v11.1.1/11.1.1a, there is no warning flagging this FCoE traffic disruption. Migrating from FOS v6.3.x To non-disruptively migrate from FOS v6.3.x to v7.0.2, units should first load FOS v6.4.1a or later (v6.4.1b should be used for encryption platforms, units operating in Access Gateway mode, or units with ports configured as EX or VEX for FCR), and then migrate to FOS v7.0.2.
