Upgrading to CCM 4.x from 3.3(5)

[ADB100]

I have a single Test Server running CCM 3.3(5) and OS Installation 2000.2.4 upgraded to OS Upgrade 2000.2.7sr5. It is a MCS7825 (Compaq DL320) with 1GB memory so I think it meets the minimum spec. To upgrade from 3.3x the documentation states I need to upgrade to the latest 3.3x release - already done - 3.3(5) - and also upgrade to OS 2000.2.7sr2 or later - again already done 2000.2.7sr5.

Do I only need to run the 4.1(3) Upgrade (ciscocm-ffu.4-1-3.exe)? What do I need to look out for? Should I forget about the upgrade and rebuild the server from scratch and obtain the original CCM 4.x CD?

I have the original OS 2000.2.4 install CD along with the CCM 3.3(3) install CD. I don't have any CCM 4.x CD's but have access to CCO for downloading anything.

I am just after some advice from anyone who has done this upgrade and any observations?

Thanks

Andy

After downloading the 4.1(3) update from CCO and attempting to install it I was presented with a a screen saying the upgrade from 3.3(5) to 4.1(3) cannot be done from the downloaded file and must be done with the 4.1(3) CCM CD's. Upgrades from 4.x can use the download.

Ah well, worth a try. I will have to wait for the CD's to arrive.

Have you tried to upgrade first to 4.0, upgrading Bars, sql, os (yes you did it) and so and then to 4.1.3???

Care with actual BARS, it creates, in last releases, .tar file incompatible if you have to start again with 3.3. So make first a 3.3 bup if you care about your configuration!!! Then try an upgrade.

You have to try, it's a test server...i made it tons of times...but i have 4.1.3 disks. I think is the same if you have the cco file.

Good luck,

I actually ended up using a Compaq SmartStart CD and doing a system erase......... Just for the sake of it.

I managed to get the CCM 4.1(2) CD's yesterday so rebuilt the server with them. It has taken me all day but I think I have most of the config back in now - I should have documented what I had configured previously but what the hey, its only a test server ;o)

Your server may not meet the requirements. In most cases the minimum is now 2 gigs. I did a 3.3(5) upgrade this weekend to 4.1(3) on 1 gig of RAM and the server would barely respond after because of memory issues. I just upgraded to 3 gigs and all is working beautifully.

I had already read the recommendations regarding memory for CCM 4.x - this is purely a test server with only a handful of IP phones and a couple of gateways, 1Gig of memory is plenty for this.

If this was a production server then I doubt I would be using a G1 DL320 anyway.......

Thanks

I just read in a CIPTT class that upgrading from CCM3.3.4 to CCM 4.0 is NOT supported. I'm assuming 3.3.5 to 4.0 is the same. Remember I didn't say it wouldn't work, it's just not supported. Since your in a Lab setup it doesn't matter.

 

[ADB100]

The release notes for 4.1(3) state that CallManager versions 3.3x and 4.x can be upgraded. For 3.3x installations the CD must be used, for 4.x installations you can use either the CD or the WEB download. There is no mention of it not being supported.

I have just read the 4.0(2) release notes and these also state the upgrade can be done from 3.3 (as well as 3.2).

I assume therefore the course contains old (incorrect) information?

Copy right 2004 so your probably right. I'd trust the Release Notes ore than the course. Now how do you answer it on the test? By the course or the notes?

 

[ADB100]

The course information is likely to reflect the test. I always remember the EtherChannel question on the CLSC course/test stating that EtherChannel can only be done between Cisco switches. The question on the test had a small image of a host with 2 ethernet connections and the question was about configuring EtherChannel to the host, the correct answer was that EtherChannel cannot be set up between a switch and a host. And we all know that is wrong....

The same course says IP Phones only respond to every other Ping. Gotta love it!!!

 

[ADB100]

If you have ever tested the PING responses from an IP Phone you would be surprised......
If you ping from a PC then you will get 100% response, but try from an IOS router or switch - you will get about 60-70% back. I raised a TAC case about this about 18-months ago and was told this is correct as the ICMP process on the IP Phone is a very low priority process.
Try it - It looks really worrying. I was pulling the network I was building at the time to bits trying to see what the problem was.
