Hi,
I'm going to downgrade a Cisco 6500 with Sup-720 from 12.2(33)SXI2a to
1.22(18)SXF17 for hardware issue.
I think I have checked everything,
Configuration issues (all commands available)
Hardware support (all modules supported)
Bootloader (not needed on sup-720 for 1.22(18)SXF17 according to Cisco
documentation)
Anyone got any more pointers I might have missed?
I tested this for SXI (not 2a) when we upgraded, and from my notes:
* If you're using VRFs and have converted the config to new-style "vrf
definition", you need to backport config
* If you've re-formatted the flash disk under SXI you should probably
(to be safe) format it under SXF before downgrade
...but other than that, if you're sure the IOS config & hardware is
compatible it should be fine - we frequently put our test/lab box back
into SXF.
