Good Morning.
I have a controller at the above release. The plan to to jack it up to MCD 8.0 latest SP. Can I upgrade straight from MCD 4.2 to MCD 8.0.
Or would it be better to go MCD 4.2->MCD6.0->MCD8.0
Also does the mitel need a passive FTP server? It's been years since I have upgraded a controller using FTP.
Reach upgrade should take around 1.5 hours? Or the AX controllers slower.
thanks
Kal.
I have done a lot of these... your plan is reasonable to upgrade in steps, I have seen too large a jump cause issues with phones taking firmware (it shouldn't, but I have seen it).
The modern versions of Mitel Software Installer do not require a stand-alone FTP server, it can handle it within the application. That said, I often use an ftp server on laptop just out of habit.
And the upgrade could take 1.5 hours, but 50-75 minutes on an AX is more common... Remember in the AX it doesn't install help files on the controller itself, so that kind of compensates for the slower system.
