[cisco-voip] Upgrading from CCM4.0 to CCM6.0

[Jonathan Charles]

Well, I have to recommend one thing, and it seems like a little one,
but I was shocked to find out that there are vendors who do not do
this....

Make sure that the partner that is doing the upgrade quotes you a
flat-rate and guarantees their work (we do), which means you may be
paying a little more, but if things go wrong, they will stay there as
long as it takes to get you up and running.

There is a vendor we compete with that quotes a flat-rate PLUS a max
hours, and if it goes over, they go into T&M mode.

Which means you can end up paying a LOT for their (or your) screw-ups...

An example, the upgrade I did this past weekend was quoted at 40 hours
(including staging), the staging took 50 hours by itself (nightmare
licensing issue with Cisco that killed three days (the license caused
CER to crash))... and then the actual, on-site part took another 30
hours... so, the customer made out like a bandit, even though our
initial bid for those hours was probably more than our competitors
(who do not do straight flat-rate)... some of the problems were Cisco,
some were the customer (DNS and Exchange things) and some ours (we
misordered  some software).

In the end, the customer had a working system.

Something to consider.
