Protection Engine for Network Attached Storage

how to upgrade Protection Engine for NAS 7.8 to Protection Engine 7.9 upgrade with 7.8 license?

Hi, do you have a answer for upgrade 7.8 to 7.9?

The software does not enforce version numbers in license files. You will keep the license file in place when you upgrade to SPE 7.9 and the product will read it correctly.

i have done the migartion thanks all of you 

its working fine but here is another confusion that i create 4 protection engine can i make than load balancer ? becuase with a single protection engine my NAS gone be hang and it take very long to get a signle file from NAS

how can i make it faster ? i dont have very big files i have small file below 100 MB but when i integrate SPE with NAS . user can get file from NAS but after a very long time maybe 15, to 20 minute 

is there any solution?

7.8 has command mode and 7.9 comes with GUI that why i need 7.9
