Re: upgrade to ccm 4.x to 6.o

Hi Hanson,

There is a Windows Upgrade process that uses a tool called DMA (Data Migration Assistant) to move your config from Windows to Linux on CCM 6.x. Have a look at this process;

Windows Upgrade

This option allows you to import database information from a Cisco Unified Communications Manager 4.x system by using a file that the Data Migration Assistant (DMA) tool produces.

From this good doc;

Upgrading to Cisco Unified Communications Manager Release 6.0(1) from Cisco Unified Communications Manager 4.x Releases

Hope this helps!

As many of you know upgrading from CCM4 to CCM5, 6 or 7 you end up losing your pins and passwords. I have an application that I have been developing that will recover these, re-populate the new CUCM version and provide for a more seamless upgrade stopping lots of calls to your helpdesk!!!
