Downgrading Your Cisco MDS SAN-OS Software Image Send documentation comments to [email protected] - IVR: With IVR enabled, you must follow additional steps if you are downgrading from Cisco SAN-OS Release 2.1.(1a), 2.1(1b), or 2.1.(2a). See the "Upgrading with IVR Enabled" section on page 16 for these instructions. - FICON: If you have FICON enabled, the downgrade path is different. See Table 9. - iSNS: The iSNS feature does not support a graceful downgrade from Cisco MDS SAN-OS Release 3.2(1) to any earlier SAN-OS release. Prior to a downgrade from Cisco SAN-OS 3.2(1), disable the MDS iSNS server and remove all configurations associated with the MDS iSNS client. Use Table 8 to determine your nondisruptive downgrade path from Cisco SAN-OS Release 3.2(1). Find the SAN-OS image you want to downgrade to in the To SAN-OS Release column of the table and use the path recommended. Note The software downgrade information in Table 8 applies only to Fibre Channel switching traffic. Downgrading system software disrupts IP and SSM intelligent services traffic.
