Difference between the Import tool and the CRM Migration tool
CRM Migration Tool relies on a step-by-step process for importing each of the five possible areas, allowing you to add data in and ensure that all of the data relationships are correctly maintained. The CRM Migration Tool has strict data integrity standards that may prevent incomplete data from being imported.
While Import tool uploads only contacts and leads.
CRM migrations require good data preparation to ensure success. It is crucial that the data to import is in the proper format for the migration to be completed in a timely manner. Poor formatting could lead to failed imports, conflicting data and additional efforts correcting data.
