Setting up a TFTP load server for CUCM 8.6 upgrade

Hello call manager wizards.

I am currently working on a CUCM upgrade to 8.6. I have a large remote office with 70 phones and a 6 Mb WAN circuit. I would like to set up a TFTP load server to load the phones code and just require the phones to hit the call managers for their configs. I asked TAC and the sent me a link saying it can be done. How do I do it? I have wintel server running the TFTP client. How do I get the correect load files to the remote server? There is no comand prompt to execute a tftp GET to the current CUCM servers.

Any ideas?

You configure your DHCP server to point to the Wintel TFTP server instead of CUCM. Then you just have to make sure the correct files are on the wintel server.
