Hi Experts,

I have a quick quesiton.
Is it possible to "downgrade" software brokers?
I found procedures for "appliance" but not "software".

Many thanks in advance,
Kia

    Hi @kiakia, there's a difference between what's** possible **and what's **supported ** :)

    The downgrade procedures do also state:

    Downgrading software versions is only supported on appliances.

    However, that doesn't mean you can't. Something you could consider is standing up a new broker running the old SolOS, running the
    show current-config -all
    command and importing that as a script to your "new old" (if you see what I mean) broker. There may be some incompatiblities, but nothing a little massaging won't resolve.

    An alternative to the CLI command, there is code somewhere there will recursively call SEMP v2 until the config is retrieved, but irritatingly I can't find it right now...

    "solacectl upgrade" command could work with an older version tarball?? :/
