I am going to be upgrading MICS from 4.0 to 7.1 and have a couple questions. All my other ones were from 5 to 6, 6 to 7 so didn't require the upgrade tool. Just wondering if folks can add to the Nortel instructions. Power down Insert 4.1 upgrade tool and power up Wait until “Insert MICS Card” is displayed Power down again Insert 7.1 upgrade tool and power up Wait until date and time display Power down third time Install 7.1 software – Is this where I install the new ROM cartridge too? Power up Do you know how long each upgrade takes on a worst case scenario,, ie, how long is too long for the phones to be flashing 😉 I was onsite today and wrote out all the programming,, just in case. If things do go south during the upgrade, if I just install the new 7.1 and ROM cartridge, will it cold start or will the sets flash indefinitely? Tackling the upgrade this Saturday, so want to have as many ducks in a row as possible.
