Enterprise Vault 11 has introduced a powerful, web-based search tool called Enterprise Vault Search (EVS). This search replaces the antiquated Archive Explorer, Browser Search and Integrated Search in a single, easy to use interface.

So you may be asking yourself, how do I take advantage of the EVS?

First and foremost, this is only available in Enterprise Vault 11 so an upgrade is the first step. Second, you must upgrade the legacy search to the EVS.
