EPDM and multiple versions of Solidworks

We're presently considering moving to EPDM from WPDM.  Being a consultancy, we must conform to our client's Solidworks version.  For WPDM, we run multiple vaults to handle the multiple Solidworks running.  Our VAR tells us a single EPDM vault can handle the multiple versions.  I'm trying to better understand the implications of this.  Is there a flag in EPDM that tells you the SW release version of the file?  Does anyone have experience with this and any precautionary thoughts?  Thanks!
