Dockit 365 Migrator uses user / group mapping to replace the unavailable user / group with valid SharePoint user / group while migration.

Source User

Dockit 365 Migrator user / group mapping enables you to load the list of source users from items to migrate.

Target User

Dockit 365 Migrator automatically loads the list of target users / group from the connected site.

You also have the option to enter the user / group of your own in user mapping.

Select Unresolved user from source combobox to map all unresolved / unavailable users from source user to a valid user in target SharePoint.
