[cisco-voip] About DMA // Upgrade from 4.1 to 6.1

Sun Jul 6 23:34:08 EDT 2008

Install of DMA requires reboot. Make sure you do the right DMA for the
right version of 6 (6.1(1a) vs. 6.1(2) )

If you don't clean up CDR beforehand, its pretty hard on the proc, but I
don't believe it stops and services. With the CPU thinking that hard on
something different than ccm.exe, the subscribers might think the pub is
offline.

One thing I noticed was if I had the same config in 4.2.x vs. 4.1.3, the
same DMA to 6.1(1a) would report certain things as a problem in 4.1 and
wouldn't even mention them in 4.2. really weird.

If it is risk vs. reward I think I will make my own decision about that.
I am asking if I run the DMA process does it cause any changes to the
call manager? I need to dump out this information and load it to a
vmware server to see if the upgrade is going to go well. 

Also back to my other question can I take this DMA file and restore it
to a VMware server to see if the upgrade process will have any errors?
Thanks.

If the answer is "yes" then you may not want to run DMA during the day.
Running DMA is pretty CPU intensive... you are writing out the entire
SQL database into flat files.

THanks alot for the help. Does anyone know or has anyone tried to use
the DMA tool and restore the information to a VMware server just to test
the upgrade? I will not have access to the hardware before I go onsite
for these customers but can get the DMA file transferred to myself. Also
can I run this in the middle of the day? Will it stop the publisher from
functioning?

Best piece of advice I can offier is to allow plenty of time to run the
DMA tool and resolve any error or warnings before your planned cutover
time. I've had upgrades with no warnings and errors, then I've had
upgrades that had two days worth of TAC cases to get it all resolved
before we got a good DMA tar file. 

On the Unity upgrades make sure that your Unity server is talking to the
nearest DC/GC (see the reconfiguration guide for details -
http://www.cisco.com/en/US/docs/voice_ip_comm/unity/5x/upgrade/guide/ex/
5xcuruge060.html). I had one  upgrade where it had attached to a server
across the WAN so the AD synch part that should have been a twenty or
thirty minute deal ended up taking five hours... not something you want
to hit cancel on in the middle, but it did mean we blew through our
maintenance window.

Speaking of upgrades, does anyone have any good resources or tips? I
have about 10 upgrades from 4.1 to 6.1 and Unity 4.0 to Unity 5.0/7.0 in
the next 6 months. I have my first one next week. Any info that could be
provided I would appreciate.

	Thanks James for your prompt response...

	We're going to use a new MCS server this new server have 2GB RAM
and 72GB HDD. However the current server only have 18GB and
unfortunately the unit C only have 2.5GB of free space. Still I don't
try to run DMA but I don't know if the 4GB is strictly necessary.

	Rgds.

	Hello,

	What is the total capacity of the hard drive? 36GB? 72GB? 6.1
requires 72GB.

	Thanks,

	Hi list,

	I have to migrate a CCM from 4.1 to 6.1 unfortunately the disk
C: space is not enough, in accordance to DMA requeriments 4GB is
necessary, so after of delete CDR and others files, I have 2.5GB of free
space in unit C: in D only 200Mbps. Then my question is: is it strictly
necessary 4GB in unit C in order to run DMA? or 2.5GB will be enough,
because I'm thinking export the .tar file in other unit (maybe network
unit) What other things can I delete into CCM in order to get more
space?

	Thanks for your suggestions.

	Rgds.
