We have Symantec Corporate AV version 8 running on our network. They're now up to version 10.
Under version 8, there was no need to renew the license for the definitions - they are required to supply them indefinitely under that license. Later they realized they could charge an annual fee and started that with Version 9.
Can anyone tell me any reasons we would want to upgrade from v8 to v10 ? I know it is "newer" but if v8 is running the same definitions, etc., as v10, am I missing something by staying on v10?
I've searched but haven't found any comparisons between the two.
