[cisco-voip] IPCC Upgrade from 3.1 to 4.0

[Voll, Scott]

Be happy it was only 4:30am.

 

My upgrade from 3.5.2 to 4.0.1sr1 was 22 hours, 3 engineers and 7
developers later.

 

I know what you're saying.

 

Scott

Oh, ran into something hilarious...

So, customer has IPCC 3.1, with standard licenses...

He has scripts with JAVA steps.

IPCC 4.0 standard does not support Java.

So, had to get a temp license from Cisco (30 days)... 

Cust is pissed he now has to buy Enhanced licenses just to upgrade his
server...

First off, don't think it is going to work, it won't. 

The upgrade process, from a procedural stand-point, is, what is the word
I am looking for... nuts.

First you spin the 4.0 CD and get a license file... no biggie, makes
sense, why install bunches of crap you aren't licensed for... 

Step two is where the world of computing loses all sense of sanity.

You are presented with a screen that has two big buttons on it... 'back
up' and 'restore' at first glance, they make no sense whatsoever, and to
be honest, I am going to give your first glance quite a bit of credit
here, because the next step you need to take seems idiotic and won't
work. 

You are supposed to go to CallManager and run BARS and backup your 3.1
data. Makes sense, you don't want to upgrade without a backup right?

OK, you run the backup, it takes a short time (for me it was about 15
minutes). 

Your next step though, seems like someone is screwing with you.

Now, remember, you just backed up your data, what do you think the next
step might be? Upgrade IPCC to 4.0? Not even a little.

The next step is to restore the data you just backed up, back to the box
you just backed up. 

And your brain is saying to yourself, 'um... the data is already
there...'

Anyway, you trust Cisco, I mean, the upgrade from CallManager 3.3 to 4.1
was so easy a child could do it, so this shouldn't be as hard as it
seems. 

The restore fails.

You try it again and again, it fails over and over with error after
error.

You think to yourself, 'just install IPCC 4.0 on top of 3.1'

Don't try it. It ain't gonna work. 

If you do try it, don't even think of selected the old 3.1 LDAP profile,
cuz then you are just going to be reminded of why everyone on Puck says,
'dude, just do a clean install of IPCC 4...'

Anyway, you call TAC, they chuckle and say, 'do a clean install...' 

So you do.

And you wander into your house at 0430, when you thought you would be
home at 9PM the previous night...
