Upgrading was a fairly simple matter - however (as usual) wasn't the same as the documentation described. Basically we were supplied with an upgrade disc and license PAK, with which you use to move to the new platform by way of a tar.gz file on the upgrade disc. Nicely, this had the big advantage of upgrading the CallManager server through the 5.1 GUI (in the same manner that you would any CM 5.x upgrade patch) and then simply rebooting into the new partition. All phones upgraded themselves - Robert's your father's brother. It wasn't quite as smooth as that though because our PAK code didn't work so we had to raise it on Cisco TAC.
So first impressions for me? Well the interface is a nice blue colour and the two great things about the 6.x GUI are the fact that the drop down box on the top right of the page now fits into a 1024x768 screen; and thankfully Cisco haven't moved things around too much - yay.
I think the first impressions were good as i'm used to the 5.x interface though those upgrading from 4.1 will find it quite tricky to navigate through for the first time.
The phones (when rebooting) now show the new Cisco logo as part of the device pack!
After the upgrade we did have a few niggles - the CM service stopped working and the service needed a kick; our MPE integration stopped answering calls because for some reason it had changed the Route List to something other than the MPE trunk; and Presence status stopped working in Cisco Unified Presence Server 6.0 and the server needed a reboot.
The only thing we haven't been able to fix is a service URL that's on everyone's Extension Mobility device profile to unlock the front door; which bizzarely has been replaced with the Extension Mobility service. In CallManager, the device profile shows the correct service URL applied to the speed dial but the phone shows otherwise. Removing the service URL and re-adding it before logging in/out of EM also does not solve the issue.
Update: None of the help pages work! They all give 404 errors - odd.
So that's the bad stuff. The good stuff is:
- We now have syncronization between the Publisher and the Subscriber so that if the Pub goes down we don't lose functionality such as CallForward status, Extension Mobility, and others
- We have mobility and single number reach built in! Also comes with new 'mobility' softkey
- Improved SRST support
- An intercom feature has cropped up in the list (woo!)
- Directed Call Park has turned up
- VERY IMPORTANT: Pickup Group Notification is back! It was missing from all CallManager 5 versions and in alot of instances this is a must have for customers!
- Slightly improved BAT tool
I'll be configuring Mobility and Single Number Reach soon! More to come!
