Hi, The migration from 3.5 to 4.0 went Ok until the last part - route points and CTI ports. The documentation informs me to delete these from CCM & then use CRS admin to re-create these. However, when doing this I get an error message "Unable to modify Callmanager". Any ideas ? I did raise a TAC case, but the engineer didn't have much of a clue & I had to revert to 3.5.
I'm sorry I don't have the answer to your question, but I'm trying to upgrade from 3.5(3) to 4.0(5) like you did and I have a question.
The procedure says to re-image the server, I'm already at 2000.4.4sr3, do I really have to re-install the OS image from scratch? If I do that, all my data will be wiped out. Can I re-install only a SR or apply the latest one ?
I just upgraded our system from 3.5(3)SR1 to 4.0(5a) over the March 3 weekend.
It was an intense process. We ran into two problems. 1) Cisco gave us the wrong license file 2) We were at BARS 4.0(8) and we needed BARS 4.0(12). The pre-install check didn't catch these two things, and it took us several attempts before the upgrade succeeded. -Just an FYI
As for the re-image, I can guarantee you that it does want a complete re-image. You need your CallManager OS install disks, latest OS Updates, and SR's. I was surprised as well that it required a re-image, but it did.
I guess that the CRS server knows at what point it is during the upgrade & so needs to be re-imaged. It doesn't take long to re-image & you have to make backups as well so you don't really lose too much.
p.s. I did it in a lab & it only took me 4 hours so not so bad.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
