Hi Rob,

First, thank you a lot for your reply.

But i'm still confused with replacement server.

Because i installed i new CCM 4.3(2) server, and i did a backup for (old) Call Manager 4.1(3) database with BARS 4.0.12.

Then I installed BARS 4.0.12 on the (new) CCM 4.3(2), but when i tried to restore the archive file i got the message

"The Cisco Unified Communications archive appears to be version 4.1(3), whereas the

installed Cisco Unified Communications is 4.3(2), you need to install Cisco Unified

Communications 4.1(3) in order to restore this data.

"

Any ideas?

Thank you

Hi NAOUFAL,

The problem here is that you are trying to go straight to Stage two of this process :( The key part of the previous post is this **"(you can't just take the CUCM 4.1(3) BARS Backup and Restore on the new 4.3(2) build)"**

During the first Stage (upgrade on existing Publisher) is when you will be asked to choose the version you are upgrading from (in your case 4.1(3))see Step 11 below. And your BARS Backup will be used here**

This first stage will be to upgrade the current CUCM 4.1(3) Pub to 4.3(2) this is the point at which the Data MIgration will take place, here is the section of the install that refers to this );

Step 10 In the Server type window, choose the Publisher radio button and click Next.

Step 11 In the Install type window, choose the Upgrade from 3.3, 4.0, 4.1, and 4.2 release radio button, enter the path to the Cisco Unified CallManager backup file in the Backup Archive File field, and click Next.

The system validates the archive file.

Then you would have to follow the steps in this doc to move the Data to the newly built 4.3(2) Publisher;

Upgrading Cisco Unified CallManager Release 4.3(1)

Replacing Servers During the Upgrade

Hope this helps!

Hi Rob,

You said "

But i thinks a I have to upgrade the OS 2000.2.7 to 2003.1.4 first and thes proceed the upgrade for the CCM 4.1(3) to CCM 4.3(2), it's that right??

because i tried to upgrade the CCM to 4.3(2) and i got the message that the OS minumum required for this installation is OS 2003.1.1

It's that correct??

Thank you in advance.

Hi Naoufal,

That is correct :)

Here are the Steps listed in the first doc I linked (these would be performed on your existing 4.1(3) Publisher;

Run the Cisco Unified CallManager Upgrade Assistant Utility on All Servers in the Cluster (Strongly Recommended)

Install the Operating System to Cisco-Provided Version 2003.1.1 (or Later) (Required)

Cisco requires that you install the Cisco Unified Communications operating system version 2003.1.1 (or later) with the latest service release before you upgrade to Cisco Unified CallManager Release 4.3(1).

Install and Configure Cisco IP Telephony Backup and Restore System (BARS) Version 4.0(12) (or Later) (Required)

If you have not already done so, Cisco requires that you install and configure the backup utility on the publisher database server.

Copy the Backup File to the Cisco Unified CallManager Server (Recommended)

Copy the backup tar file from the remote location where you stored the file to the local hard disk of the Cisco Unified CallManager server so that you can easily access the backup file during the restore process. (Recommended)

Removing a Drive, Inserting a Replacement Drive, and Drive Mirroring (Strongly Recommended)

Item Needed: Newly Purchased Hard Drive

You cannot remove a drive if you have the Cisco MCS-7815, MCS-7820, MCS-7822, or MCS-7825 Cisco Unified CallManager appliances, or the customer-provided IBM xSeries 330 server.

After you verify that you have a good backup of the data, you can remove a drive to save configured data; however, you must insert a replacement drive into the server before you begin the operating system procedures. This task may require that you purchase a new drive.

**Upgrading Related Cisco CallManager Services and Detecting the Server (Required)

Continue the upgrade by performing the following procedure.

--------------------------------------------------------------------------------

Note Critical third-party components that are required and installed by Cisco Unified CallManager might require multiple reboots during installation, and you may need to manually restart the installation program and reenter the configuration data.

--------------------------------------------------------------------------------

Procedure

--------------------------------------------------------------------------------

Step 1 If you did not log in to the server after the operating system upgrade, log in to the server by using the Administrator password.

Step 2 Locate the Cisco Unified CallManager 4.3 Installation, Upgrade, and Recovery Disk and insert it into the drive.

The installation process automatically starts.

--------------------------------------------------------------------------------

Tip Do not remove the disk until you are directed to do so by procedure.

--------------------------------------------------------------------------------

Step 3 To confirm the version of Cisco Unified CallManager from which you are upgrading and the version to which you are upgrading, click Yes.

Step 4 To confirm that you have disabled antivirus and intrusion detection software, click Yes.

Step 5 To confirm that you might be prompted to reboot the server and reenter configuration data multiple times for Cisco Unified CallManager to install critical third-party components, click OK.

Step 6 In the Welcome window, click Next.

Step 7 Accept the Cisco Unified CallManager license agreement by clicking the I accept the terms in the license agreement radio button; then, click Next.
