Customers who have Symantec Endpoint Protection 11.0 have the following downgrade options to Symantec Antivirus 10.x:
1. If customer has Symantec Endpoint Protection 11.0 BUSINESS PACK, customer can have a downgrade license file for Symantec Antivirus 10.x. For renewals, this can be obtained by registering the serial number (for recent orders, Symantec has now started sending out certificates with the license files attached to it so you can skip the registration part) in the License Portal. For new purchases and if no license file was generated after registration, Customer Care can provide downgrade license files.
2. If customer has Symantec Endpoint Protection 11.0 (volume license), customer's downgrade option is to download Symantec Antivirus Corporate Edition 10.x, this version of Symantec Antivirus is the one that doesn't need a license file but it has the same features as the one which has the license file.
If customer doesn't want to download and install Symantec Antivirus Corporate Edition 10.x and wants to get just a license file, he can return his Symantec Endpoint Protection 11.0 to where it was purchased (if it's still within the return period) and exchange it with Symantec Endpoint Protection 11.0 Business Pack. The keyword here is Business Pack. If you need a license file, you must see BUSINESS PACK in the product description on your certificate.
