Hello,

I agree with above comments.

This is 1 area where you would require assistance from a Symantec Partner.

As we do not know the Current / Existing Infrastructure and neither we know the dependency in that environment.

To find a specialist in your area, visit the Symantec Partner Locator.

If possible please provide me some related documents. Please.......

Minimum recommended server configuration for SEP (need clear proof/reference document from Symantec)

--> With every release Symantec will provide system requirements document, you should check the same.
