SQL Server 2005 doesn't have an upgrade license available so you have to purchase a new SQL Server 2005 Enterprise license.
If you are using CPU licensing the licenses retail for $25,000 US per CPU. If you are using CAL based licenses then the server license cost retails for $13,819 US. If you are using CALs you do not need to repurchase your CALs as CALs are not edition specific.
