'Migrate data from Dynamics CRM 4.0 to 365

I have a client with an old CRM, Dynamics 4.0 on-premise and I want to migrate data from his CRM to a new instance Dynamics 365. Is there any way to migrate his data?



Solution 1:[1]

Consider SSIS + KingsWaySoft adapter. Read the CRM 4.0 data directly from the SQL Server database using the standard SQL adapters.

Solution 2:[2]

Moving from 4.0 to Dataverse is not easy... Its likely easier to migrate the data into a net new online instance after recreating the 4.0 datamodel and customizations... Alternatively,you can always do in place upgrades up to a supported version to do a fast track migration with Microsoft help. https://docs.microsoft.com/en-us/dynamics365/fasttrack/migration
