Use the drop-down arrow to select the Target Exchange Mailbox Database where the new mailbox(es) will be created.
By default, all mail, calendar, and to-do information is migrated. You can limit the information that is migrated based on the document's creation date. If you want to only migrate mail as of a specific date, select the Migrate mail created after check box and then select the appropriate date using the drop-down arrow. If you want to migrate mail created prior to a specific date, select the Migrate mail created before check box and then select the appropriate date using the drop-down arrow.
The If message already exists in Exchange mailbox field's default setting is Merge new messages with existing messages. This setting indicates to the migration engine that if a copy of a mail message already exists in the user's mailbox, the message should not be duplicated. If you select Delete existing mail, the migration engine deletes all mail from the mailbox prior to migrating mail from Domino. If you select Add to existing mail, the migration engine migrates all mail and duplicates are created if a message already exists in the mailbox.
