I want to migrate approx. 10 users from an on-premise Exchange 2003 to Office 365. I was wondering, if there are any drawbacks when I transfer existing content via PST export/import only. So not using any of the standard migration paths (ie. cutover).
I'd love have a chance to decide individually, which objects (Mails, Contacts, Appointments, etc) will be transferred to Exchange Online.
Do I miss something? What will the "cutover"-method do in addition? Which problems could arise, when PST is the only "means of transport". What will be missing?
Are there third-party tools for anlayzing, checking, cleaning ans preparing PST files?
