Compare MVD Versions

Use the Compare feature to compare two specification versions of an MVD side by side. This helps you identify differences in column definitions and configuration settings, including items that were added, modified, or are not available in one of the selected versions.

Use the comparison to understand what changed between versions before reviewing, approving, certifying, or consuming an updated MVD.

Note:

The comparison view is read-only and does not modify either MVD version.
