Hello Jose
  
  In order to migrate the licenses from your existing RFS-7000  to the newly installed VX-9000 you should start by reaching out to your Extreme  account team.   The Extreme account team  will work with you to complete a license migration form that they will submit  to the Extreme GTAC.  Once the licenses  and Access Points have been migrated to the VX-9000, your account team will  work with you to ensure that the licenses are decommissioned on the RFS-7000. 
    As far as the configuration goes, it kind  of depends on how complex your current RFS-7000 deployment is.   Typically, we would recommend you rebuild the  config from scratch when moving from one platform to another, but technically you  could use portions of the existing RFS-7000 configuration to piece together a  new configuration for the VX-9000.
