Products
Matrix N-Series DFE
Firmware 7.11.01.0025 and higher

Changes
Upgraded DFE from pre-7.x to 7.11.01.0025+ firmware.

Symptoms
Lost configuration.

Solution
Before upgrading, please review the 7.x firmware background information in 'Transitioning to Firmware v7.0'.

Version 7.11.01.0025 and subsequent versions utilize a new internal "binary" format for storing configurations. In addition, some of the CLI command structure has changed.

Version 7.11.01.0025 or newer firmware will clear an internal configuration that was written in the older format. To avoid loss of configuration during an upgrade you must take specific steps to create and restore an ASCII configuration file, which also automatically converts the previous command syntax to the new syntax. Simply upgrading the firmware will not perform this set of important tasks.

Here is the recommended procedure for upgrading from pre-7.x to 7.11.01.0025+ firmware:
  1. Install and run 6.x version 6.11.01.0040 or higher (9430).[list]
Note: Get both 6.x and 7.x firmware here: Diamond / Platinum / Gold.
  • Issue the 'show config outfile <slotx/myconfig>' command (where x is the chassis destination slot number); which will locally save your configuration to an ASCII file located on the slot x module.
  • Download, but do not boot, the 7.11.xx.xxxx firmware.
  • Issue the 'set boot system <imagefilename>' command, then choose the "don't reset" option:This command can optionally reset the system to boot the new image.
    Do you want to reset now (y/n) [n]?n[/code]
  • Issue the 'config <slotx/myconfig>' command (where x is the chassis source slot number from step 2); which will reset the system, boot onto 7.11.xx.xxxx firmware, and restore the configuration from the ASCII file located on the slot xmodule.[/list]General upgrade procedures are explained in 5040.
    Configuration file manipulation is explained in 5035.
