DMA download link and usage instructions are available at the following link. You will first need to build CUCM 7.X on MCS and upgrade it to 8.x / 9.x on MCS depending on whether your MCS server supports it. Then take a backup and build same version on UCS and restore the backup. Detailed procedure is available on callmanager install and upgrade guides which you can get by using google search.
you can download the DMA tool
but with DMA , you can go upto call manager 7 only.
you can also refer the upgrade path to desired call manager version by referring software compatibility matrix.
But what I suppose BE7K comes pre-loaded with CUCM 9.1(2). Also, whether BE7K supports CUCM 7.1(5) is not clear.
you can speak to cisco SE for more details.
