I been trying to research this possibility of Transfering Data from one Onlien 365 CRM platform to another 365 Domain area where we will purchase a CRM add-on. The goal is to have our CRM integrated into my existing Domain Admin portal instead of having two separate domain admin areas. Example : our crm is .onmicrosoft , our other 365 which host our Exchange, AD sync etc.  is Company@domain.com

I see that when I am in Microsoft CRM, there are exportable options for certain data, I am wondering if Microsoft or any third party software can export all data and import into another CRM instance. Or if the export to CSV is the only option for data. I am just trying to make sure that all data can be transferred
