Most users migrate OST to PST files in such a case. Because OST is not compatible with Windows Outlook, and converting it to PST apparently gives a way through that. But I suggest taking a much better method. It can auto-load Outlook identities folders by itself. Naturally, this makes it a lot easier, but most importantly, it makes the migration accurate safe. If data loss is your biggest concern, you should definitely try this one out. You can’t go wrong with OST to PST Converter. Refer:- https://www.outlookconverter.net/ost-to-pst/
