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.

Although you can only take snapshots of the local installation, you can compare configurations on remote installations (even on different platforms) by making the snapshot file from one machine available to another machine that is running VCDA. The snapshot file is a simple text file that is readable across different platforms.
