[cisco-voip] CUCM 8.6 promotion of new pub

[TG]

Hi Charles, I'm not promoting a sub into pub, rather moving phones to 
the other cluster. If you meant segregated planned controlled outages, 
then that can't be done as "ALL" phones take a hit by cert combination 
regardless of which sub they are registered to.  My only ask was to see 
if that reset could be prohibited so phones could be manually reset in a 
controlled and clean manner. Comparing this with firmware upgrade, the 
process itself doesn't initiate a reset to 'ALL" ones in one shot so you 
have control over how you want to bulk that activity, either server 
level or DP level etc.

Thanks,
TG

    TG, you state that you aren't trying to promote a sub, but your
    subject line indicates that you are.  When talking about combining
    certs and TVS restarts, thats for a migration, moving phones from
    one cluster to another.  This is not a way to promote a sub to a
    pub, which you cannot do.

    If you are upgrading while rebuilding a new cluster, that is one
    thing, but we don't do this often, and most customers do not ever do
    this.  What I mean by this is if you are building a fresh, new
    cluster with the latest version and then moving phones to this new
    setup.

    Rebuilding to resolve dial plan best practices or splitting a
    company are the only reasons I've seen the need of a migration, but
    perhaps moving a group of phones from one cluster to another in a
    very large deployment could be a practical use of it.

    Pushing new certs down (by combining them) is going to cause some
    restarts of phones, plan for that with your outages.  It's really no
    different than planned outages around upgrading firmware in prep for
    a software upgrade, which causes another round of resets as they
    re-register with subs.

    Good luck and ask your questions, but please clarify your plan and
    intents.

        Brian,
        Thanks for your input. It's unfortunate we have to live with it.
        Need to know the significance and purpose of TVS restart on
        subs, as results are seen without doing it as well. Also does
        that cause another reset on the phones?

        Ryan,
        Maybe you misunderstood it, it is about bulk cert, and not pub
        recovery. Do you know of a way to stop phones from resetting
        just by combining the cert? We see this being fixed in 9.5 but
        not everyone is willing to jump to 9.5 for this gap. Cisco
        should consider addressing this on 8.6 and 9.1 as well as many
        customers are using these releases. If your 30k phones have to
        take a hit because of cert combining, then that's a big drawback
        to this whole procedure of cluster replacements.

        Thanks,
        TG
