Hallo,
last week I set scheduled upgrade SEP clients over night (one group, cca 20 clients). Version from 12.1.1000 to 12.1.4104, silent upgrade, delayed restart, maintain communication settings. Upgrade is done and all clients are up to date.
BUT
the first time i run console a saw EACH client THREE times, one online and TWO offline (one with old "last time connect" and one with actual!). After manual deletion BOTH offline clients, one of then re-appered again! It disappeared after second deletion. And, some clients changed group!! Some of them I found in default group and some of them in another group. Fortunatelly this is a very small site with one domain and a few groups. I do not want imagine what should happen in site of another customer with more than 20.000clients with hundreds groups and many domains...
I work with SEP/SEPM for many years (from AV 8.0) but I have never seen this behavior before (yes, sometimes duplicity, sometimes "magic" teleportation client beteween domains in version 10-11.x but NOT like this and with version above 12.1).
Any Idea please before I start set upgrade for next group?
Thank you, Ondrej
