Microsoft Dynamics CRM on-premises Migration to Microsoft Dynamics CRM Online

Hi,

I want to migrer Microsoft Dynamics CRM on-premises 2015 to Microsoft Dynamics CRM Online 2016 without use service Scrib or another service.

the steps I want to use is:

1 : export a special solution called the Default Solution. The Default Solution contains all the components in CRM and import in CRM Online.

2 : Export Data to Excel for all entities in CRM on-premises and import in CRM Online.

3 : map users CRM with AD Office 365.

Is this correct steps?
Any another way to migrer or ideas ?

Thanks in advance.
