[cisco-voip] CM 5 -> 6 upgrade issues

[Ed Leatherman]

Hi folks, had some issues after upgrading to CM 6 this weekend from version
5, and ended up backing out of the upgrade and rebooting back to version 5.
Curious if anyone has seen the following issues after upgrading to CM6:
- Lines on some phones disappearing from the phone and from callmanager
- ring settings on lines being changed
- phones registering but not getting calls
- 7914 expansion modules not coming up
- Some phones not registering at all

So far the only commonality I can figure out between the phones
w/disappearing lines, is that they were programmed back in CM3.X with line2,
line3, line4 etc line appearances of the same DN, instead of 1 line button
with multiple max call appearance/busy trigger.

I did not have the opportunity to do much troubleshooting before changing
back.. our post-upgrade tests worked fine and I didnt know there were issues
until after we were back in production time. Since I have a list of specific
phones that had issues, i'm going to build a CM5 pub in the lab and restore
a recent backup, then upgrade to CM6 and see if the same problems come up
with it so I can actually troubleshoot.. provided I can get around licensing
problems with that.

I was expecting this to be an easy upgrade, and the upgrade process itself
went off without a hitch, but ended up being the first one i've had to
totally back out of.

Thanks!
