5.6.4.1.   Add Source Classification

You can add and map Custom Source Content types (Source Classification) by clicking on "Add a new source classification"  icon. Each classification has its own unique set of metadata which can be mapped to the appropriate Target Content Type.

For example, file shares save images as document content types. SharePoint has a provision to save all the images with content type as “Image” rather than “Document”. To allow a proper mapping, Migration Accelerator provides “Add a new source classification” functionality in the Content Type Mapping Settings screen.

You can assign custom content type to a particular document type (e.g. Images having extension “.jpg” or “.png” in the Name field).

The “Add Source Classification” screen has a “Script Evaluation Area”. This can be used to evaluate the added scripts to verify whether they are correct.

See the image below for an example:
