Hi,
There are two products i.e SEP 12.1 Enterprise Edition (EE) & SEP 12.1 Small business Edition (SBE )
Both products have different functionality when we talk about licenses.
You can install SEP clients as per license agreement.
What will happen if you overdeplyod licenses ?
In SEP 12.1 EE after grace period expiry you & your partner will receive notifications about same but you will receive updates from Symantec.
In SEP 12.1 SBE after grace period expiry you & your partner will get notification about same & you will NOT receive any updates from Symantec all sources.
