Backup Exec 2014 Small Business Edition w/support moving to 2015

If an existing customer with Backup Exec 2014 Small Business Edition has active support\maintenance for two more year can they upgrade to Backup Exec 2015 using File Connect.  If so I assume they will have access to licensing for Backup Exec Server plus agents for Exchange, AD, SQL, SP and Hyper-V.  The licensing guide seems to state this from my read of it   I ask because the migration path is to Bacukup Exec Capacity Edition Lite 1TB and that is what will show on an IBR, but if the customer had greater than 1TB front end they have to purchase additional capacity licensing if they move to that licensing model before thier support expires in two years.
