How can we set-up Enterprise to play nice with Toolbox?

How can we set up Enterpise to support multiple versions of Solidworks (ie. SW 2010, 2011 & 2012)? Each version of Solidworks will need to point to a version specific Toolbox.

Setting up three vaults for each Solidworks version is not supported by SW since they have no tool to migrate a program from say SW2010 into SW2012. This functionality exist in Workgroup using the pdmexport.exe and pdmimport.exe.
