Hi Daniel,
Thank you for choosing AkrutoSync.
This is Brian, one of the support representative of Akruto.
Akruto initially syncs data from Outlook to your phone / tablet. If Outlook already has data from your iPad Mini then it should be able to sync these data back to both of your devices (iPad Mini / iPad Pro)
You can try out the software and see if it works for you. You can download the 7-day free trial here: https://www.akruto.com/get-akruto-sync/
Regards,
Brian Tan
