The Catalog Section shows the list of sources matching the currently set filters, in the order specified by the Sorting Selector.
The terms "source" and "sources" refer to a database or database cluster throughout this page.
Sources that have been excluded via the Sources page using database or cluster exclusion are not displayed on this page.
Catalog items are collapsed by default and can individually be expanded. The item layout has the following sections:
Catalog Item Header
Each item shown in the catalog contains a
The shading color is red.
The shading color is blue
The shading color is gold
The shading color is black
The database icon is made of 3 segments. The segment shading indicates the data volume in the corresponding source. One shaded ring indicates a smaller volume, and 3 shaded rings indicate a large volume. The volume calculation is total across the source in all schemas, databases, tables, collections, etc.
Shading colors for the various DB engines in this context do not relate to migration complexity. The shading merely associates the source to the various DB engine types.
To see the full analysis of a source, click the icon at the top of the catalog item. The individual database page opens, and the currently selected target is chosen for the analysis shown on that page.
Catalog Item Migration Complexity
The migration complexity bar shows the relative complexity of migrating the source to a certain target. When a different target is selected, this complexity can change.
If no target is selected in the Filters section, the migration complexity section on each catalog item is not shown.

Catalog Item Detected Features
Catalog items contain a scrollable list of features.
The features are ranked by impact: features with high impact are shown on top, followed by features of medium impact, then low impact.
Feature impact is indicated by the accompanying icon color:
Red: high impact
Orange: medium impact
Green: low impact
The impact of a feature changes based on the migration target. If a different target is selected, a new list of features is generated. This can cause a feature that previously appeared for the old target to appear differently now that the new target is being used. Each feature may:
Not be relevant in terms of complexity for the new target, and therefore not appear at all.
Have a different impact level and therefore be shown with a different color.
