ICX7450 OS

[zachary_hull]

I am running ICX7450's and some of our switches were pre-maturely upgraded to 08.0.92.

I would like to know if it is possible to migrate the OS from 08.0.92 [backward] to 08.0.90.

Has anyone tried this before?  Is there a procedure for this?

Please, advise.

What are you using to push the code? Generally most customers initiate the copy from the switch CLI and use TFTP or SCP.

Question:

Does "primary" need to be in the following output:

SSH@ICX7450-24P Router#sh files
Type       Size   Name
----------------------
F        32172120 secondary
F          162204 poe-fw
F             823 startup-config.txt
F             256 secondary.sig
F            1576 $$ssh8rsahost.key
F             256 primary.sig

If there is a valid image in primary flash, yes you should see primary in that list.

We use SCP via CLI on the server.

So you do not use 'copy scp flash' command? You are doing something like this?

pscp60 <filepath>\<filename.bin> <username>@<ip-addr>:flash:<pri/sec>:<filename.bin>

pscp60 SPR08090kufi.bin username@10.200.130.4:flash:pri:SPR08090kufi.bin

It has been a long time since I have pushed from CLI of the SSH/SCP server, but that was an example I had saved. Sometimes we get syntax issues especially with the second time we type the filename.
