[cisco-voip] Moving / Upgrading 4.1(3) to CallManager 6.0 ?

[d4rk f1br]

Starting to 'look' at what all is involved with moving or upgrading to CM
6.0.  Currently running CM 4.1(3) on two older MCS servers, just a publisher
and subscriber.  If the budget allows I am hoping to actually purchase new
hardware for this and possibly run both versions in parrallel for testing
and what not.

Couple of things though I am concerned with is that I seem to recall hearing
something about licensing on 6.0 for phones?  Apparently Cisco has
introduced some new licensing stuff with 6.0 that reminded me of unity
licensing in a way.

I suspect that by moving to 6.0 I would also have to look into Unity and
IPCCX compatibility issues and the best way to address dealing with all
things at once.  If CM 6.0 requires IPCCX 6.0 and Unity ? well thats a
pretty big deal and really makes upgrading a huge pain in the arse
obviously.  Its often difficult enough to upgrade one thing and deal with
those repercussions for a while, but to have to do all together well thats
just gonna suck.  :-)

To me upgrading to 6.0 is really not something I believe is worthwhile as I
don't see what we are really going to gain from it.  However I am a tad
concerned about letting things age you know, both hardware and software.  I
do see some possible benefits and features in some of the newer versions of
either IPCCX and Unity, but those typically say you need your CallManager to
be a new version.  So as long as I stay humming along with 4.x, which in
itself may be sufficient I can't leverage some new feature I see available
in one of the other products.

And finally I guess I would have to ask does anyone know the latest news on
7.0 ?  I have heard and read about release dates in early 2009, but
obviously nothing is concrete of course.  It does however leave the person
like me wondering what to do of course.  Even if I were to dedicate myself
to saying yes I am going to move to 6.0 this year, well it would like not
happen to Q3 or Q4 at which time we may very well be hearing about actual
7.0 release dates being only months away.

Its sad that things have become what they are if you ask me.  So many
versions in so a relatively short time.  Whats worst is the people on the
fringes of things, the people who happen to hear about this release or that
and so they question why we are "so far behind" on our callmanager versions,
or who hear about an upcoming callmanager release and wonder when will we
move to this or that.  Its gotten to be about as bad as trying to keep up
with Windows versions almost.  Never thought the phone system would become
like this.  Is it the price you pay for innovation?  And is there really all
that much innovation to warrant it?  Who knows..
