Scan Engine EOSL and definitions

Hi we're still running Scan Engine 5.x which I understand is now well and truly EOL (as of March 2014), but die to other technical factors, such as our servers hosted by VMWare 4.5 we are unable to upgrade currently to Protection Engine.  Adding to this, a recent network change by the customer's network sullier has rendered all direct updates unfeasible meaning we need to implement an internal liveupdate server.

Will it still be possible to update Scan Engine from Live Update and how long will the definition files still be compatible with scan engine 5.x products?

Will it be possible to set up a Liveupdate v2 server to disseminate virus definition files to these old Scan Engine servers?

Thanks

Steve
