Unity
=====
With Unity 4.x to Unity Con 8.x i just build Unity Conection on a server and will import the users. Read the migration manual and seems allot of work for little gain.
Steps
1) Build Unity Conection server and integrade to CM
2) Email Licensing with the unity licence files and your UCCS contract number. They will email you back the converted unity con licence
3) Go to http://www.cisco.com/go/license and add the PAK from part code UNCN8-UTYMIG-K9 (Need to order it through the PUT tool with your UCCS contract number). This will give you the migration licence to add to unity con

UCCX

Just a note on UCCX. If you upgrade from 8.0 to 8.5 the you need to order a upgrade licence through PUT. Part code:CCX-UPG-E-80-85K9= CCX ENH 8.0 to 8.5 ENH EUCSS Major Upgrade Dont need to do this for Unity or CM for the same verstion upgrade
