How to add additional EV services to configured EV server?

Hi,

I have an EV environmeant that has 3 EV servers in 1 site. EV1 was the first one and has been handling all the indexing and stroraging. 2 more EV servers, EV2 and EV3 was added to the environment. Now how ever I noticed that the additional EV servers only has these services installed:

Enterprise Vault Admin Service, Enterprise Vault Directory Service and Enterprise Vault Task controller Service.

If I'm not mistaken every EV server has to have also the Shopping service installed, correct?

Since the EV1 is still handling all the indexing and storaging the other services are not needed, right?

Now how do I add the Shopping service to these already configured EV2 and EV3? Or is a new "clean installation" necessary?
