Upgrading 20x EV FSA from 10.0.1 to 10.0.2

Hi,

We want to upgarde 20x EV FSA from 10.0.1 to 10.0.2, so basically the steps would be 

1. Stop services in all 20 EV FSA Server

2. Upgrade the first EV Server and start Directory service, wait for event log, start storage wait for event log and start all other services

3. Upgrade rest of the EV servers one by one and start services

Correct?

Many Thanks
