The Item manifest is a package of data that contains all necessary metadata associated with the item to be migrated.  The manifest content is migrated along with the item content in Step 4.

This step populates the Item Manifest for each item by:

• Creating target metadata by using the assigned Target Content Type to apply appropriate metadata processing to the source fields.
• Creates structure mapping metadata by evaluating structure mapping to determine target location to migrate the item to.
• Creates security information metadata by evaluating security mapping. 

In Items List the status will be ‘Transform’. 

NOTE: If the option to ‘Update Embedded Links’ is enabled in General Settings, it is essential that ALL ITEMS are first processed ONLY to Step 3-Transform.  This is because this step determines the target locations of items which is then used in step 4 (Migrate to target) to replace existing embedded links with links to the new location items will be in once actually migrated.  See 11.3.
