You can nondisruptively downgrade directly from SAN-OS Release 3.2(1).
Use the interface shutdown command to administratively shut any Fibre
Channel ports on Generation 1 modules that are in an operationally down
state before nondisruptively downgrading from SAN-OS Release 3.2(1) to
SAN-OS Release 3.0(3b) or SAN-OS Release 3.0(2), and then to SAN-OS
Release 2.0(2b). An operationally down state includes

Downgrade to SAN-OS Release 3.0(2). Use the shutdown command to shut
all the ports operationally down and administratively up on all the
Generation 1 modules before nondisruptively downgrading to Release

On a system with at least one SSM installed, the install all command might fail on an SSM when
you downgrade from Cisco SAN-OS Release 3.2(1) to any SAN-OS 2.x release earlier than
SAN-OS Release 2.1(2e). Power down the SSM and perform the downgrade. Bring up the SSM with
the new bootvar set to the 2.x SSI image.
Downgrade the SSI boot images on the SSMs on the switch to a release version supported by your
Cisco SAN-OS release. Refer to the
Service Interface Images.
