If you have Office 365 Shared Mailboxes that you want to migrate to some other tenant, then you need to right-click on the particular mailbox from the source list and ignore the Office 365 license validation.
Important Note: Make sure that you perform the above step with Shared Mailboxes only. If you ignore O365 license validation of a user mailbox, then that user mailbox won't be migrated.
