If you are running ES 3300/4300/8300 devices, they are already EOL as they are running on 32-bit systems and older hardware.
We have a new line of product to replace the same in 64-bit environment which is 64-bit E-mail Security Software.
We highly recommend that you migrate from an older device like 3300/4300/8300 units to newer ES Software as soon as possible due to limitation on 32-bit system and take the advantage of our new 64-bit ES Software.
For more details on the license purchase or existing license transfer from 3300/4300/8300 to 64-bit ES Software, please contact your reseller or sales representative.
To migrate from the ES 3300/4300/8300 to ES 64-bit ES Software please follow the steps as mentioned below:
If you are running an older firmware, please first upgrade your appliance to 9.0.x version or later
