VCDA allows you to compare the current configuration of the local installation with a previously saved configuration snapshot. It also allows you to compare two saved snapshots that do not include the current configuration. VCDA also indicates, using an icon color, if the difference is due to a parameter that is different in both snapshots, or a parameter that exists in one snapshot but not in the other.

If there are no differences in the main parameters, VCDA displays a green icon and a message. If there are no differences in the other information, VCDA displays only a green icon.
