Have a client running CCM Pub/Sub v3.3 on MCS 7835/7825servers with mirrored 36.4GB hdds, 1 GB Ram. Pre-sales support has indicated that these server are near EOL. Unity is on a 7815 tower server, also near EOL. Looking at new servers for each. Question I have is:

If I get new servers and the upgrade licenses with support, is there a way to migrate the existing databases for CCM/Unity to the new servers during the installs?

Unfortunately it is not possible to do a direct upgrade from CUCM 3.x to 6.1 without first upgrading to CUCM 4.x.

The direct upgrade from CUCM 4.x will then only be possible with the DMA (Data Migration Assistant) tool.

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 supported versions of 4.x to Cisco Unified Communications Manager 6.1(2) by exporting this data in a format that Cisco Unified Communications Manager 6.1(2) can read

The above is taken from this document:-

For supported Cisco Unified Communications Manager Upgrades for Release 6.x and Release 7.x take a look at this doc:-

Upgrading to Unity and Windows Server 2003 on an existing Cisco Unity server is supported only when you back up Cisco Unity data by using the Cisco Unity Disaster Recovery Backup tool, reinstall all software on the Cisco Unity server, and restore Cisco Unity data by using the Cisco Unity Disaster Recovery Restore tool.

The following is comprehensive guide from upgrading from Unity 4.x to Unity 5.x

Hope these help.
