Transparent upgrade between two GlobalProtect releases in the same release train is currently not supported. For example, you cannot do a transparent upgrade from GlobalProtect 6.2.6-c700 to 6.2.6-c857. To enable easier transparent upgrades, we have re-packaged 6.2.6-c857 as GlobalProtect 6.2.7. Customers looking to upgrade to 6.2.6-c857 can use 6.2.7.

GlobalProtect 6.2.7 includes no additional bug fixes compared to GlobalProtect 6.2.6-c857.
