DMA with CCM 3.5 to CCM 6.0

[bilalghayad]

Hi Forum;

As I have currently CCM 3.5 and need to install CCM 6.0 linux based, then need to use DMA to migrate data from CCM 3.5 to CCM 6.0, th question is:

Can DMA be used to migrate data from CCM 3.5 to CCM 6.0 or the source CCM should be 4.1 or 4.2 only? So, do I have to upgrade the CCM 3.5 to 4.1 and then use the DMA to do the migration.

Any help?

Hi Bilal,

This will have to be a two step process to get to CCM 6.x. DMA can only be used with CCM 4.1 and CCM 4.2.

DMA migrates data for Cisco Unified Communications Manager and Cisco Emergency Responder, as specified in the following sections.

DMA assists you with the first step in migrating Cisco Unified Communications Manager data from versions 4.1(x) and 4.2(x) to Cisco Unified Communications Manager 6.0(1) by backing up this data in a format that Cisco Unified Communications Manager 6.0(1) can read. Cisco Unified Communications Manager 4.2(x) and older versions runs in a Windows environment, and Cisco Unified Communications Manager 6.0(1) runs in a Linux environment, so DMA exports Windows-based data to a format that Linux can import. The Cisco Unified Communications Manager 6.0(1) installation process converts the backed up data as needed for Cisco Unified Communications Manager 6.0(1), which completes the data migration.

DMA saves the data that it exports in a tape archive (TAR) file in a location that you specify.

You must install and run DMA on the Cisco Unified Communications Manager publisher server before you upgrade to Cisco Unified Communications Manager 6.0(1). If you make any configuration changes after running DMA, the system does not retain these changes when you upgrade.

In addition to exporting Cisco Unified Communications Manager data, DMA exports data for these related applications:

Cisco Unified Communications Manager Attendant Console (AC)

Cisco Extension Mobility (EM)

Cisco Unified Communications Manager CDR Analysis and Reporting (CAR)

Certificate Authority Proxy Function (CAPF)

Certificate Trust List (CTL)

International Dial Plan (IDP)

DMA does not export this information:

Custom Music on Hold (MOH) files-You must reapply these files after you upgrade to Cisco Unified Communications Manager 6.0(1).

TFTP phone load files-You must reapply these files after you upgrade to Cisco Unified Communications Manager 6.0(1).

Files on Cisco Unified Communications Manager subscriber servers-Subscriber servers obtain required information from the publisher server as part of the Cisco Unified Communications Manager upgrade process.

Hope this helps!

Hi Rob;

So that means also we can not migrate the data from CCM 4.3 to CCM 6.0, as it is only from 4.1 or 4.2? Is it correct?

Hi Bilal,

CCM 4.3 to 6.x is not shown as supported. Have a look at this good doc;

Cisco CallManager Upgrade Paths

Hope this helps!

Very nice document :) - Thanks a lot.

We have the hardware MCS 7835H which contains old CCM (3.5) which is windows platform, this server can be used if we need to install (a fresh) CCM 6.0 ? How can I know the needed hardware for this CM 6.0, searched for that but did not find exactly sheet, can you help?

And really a special thanks.

Regards

Hi Bilal,

You are always welcome :)

This doc shows the Server support for all CCM Versions. The 7835H should be good to go;
