ICX7650 switch image to router image upgrade issue

[dawidku]

We loaded image 10.0.10a on a core ICX7650 single unit switch (originally running version 08095j ), upgrade was successful and all settings converted OK from switch to router however most of the connected access switches (Ruckus, Cisco) lost connectivity after the upgrade.

Eventually restarting the core ICX7650 switch all returned to normal but seems like an additional reboot is required after firmware upgrade.

Did anyone else experience this kind of behaviour during upgrade?

Hey @dawidku 

I just wanted to be as transparent and straightforward with you as possible. We put those code recommendations out on the support portal to put our customers in the best position possible. Again, you can certainly run 10.0.10a and it is surely supported. If I am being blunt, downgrade is going to be quite a pain, so you will may want to assess and decide if it is worth the hassle for you. There will not be a nice, automated way to do this via SZ due to all the syntax differences, but you should be able to pull your old 8095 configuration from there (Network > Switches > Configuration Restore > Config Download).

From there, you would need to do something like this:

*Load 8095J router image (TNR08095jufi.bin) to flash (copy tftp flash <tftp-serv-ip> TNR08095jufi.bin primary)

*Copy your 8095 backup configuration to *startup* config from CLI (copy tftp startup-config <tftp-serv-ip> <startupfilename>)

Do ***not*** wr mem or you would overwrite the copied the startup config

*reload into 8095 image and startup config

If you do decide to stick with 10.x, I would just recommend upgrading patch by patch as they release. Each patch will bring some additional stability.
