we've recently upgraded our UCM cluster from 6.1 to 7.0.2 on new hardware. We changed the tftp-server in the dhcp scopes and made a reset of the phones on the old cluster. after contacting the new tftp-server (new publisher) the phones loaded the new firmware and registered on the new cluster. so far so good, but we've problems with our ata's. They got the new tftp-setting by dhcp but they didn't load the new firmware. It seems, that are no .cnf-files on the tftp for the ata's, because they have a "SEPDEFAULT.cnf" as tftp-file. futhermore the ata's are still registered on the old cluster. As workaround, we've added the new publisher as a static ip directly on the ata (webinterface). So what can i do?
