Cloud Migration Base Extension
This extension will take you through the process to configure a connection between your on-premises solution and your Business Central online environment when you start the migration to the cloud.
Once the connection is configured, you can migrate data from your on-premises solution to Business Central online. This extension will work in conjunction with a data replication extension available for your specific on-premises solution. For more information, see Running the Cloud Migration Tool.
