I am looking to migrate the CRM 2013 On-Premises instance to latest Dynamics 365 Online. I know for transferring data there are some third party tools available. I am not sure if Configuration Migration tool (bundled in CRM SDK tools) will do the same.
Below url says the tool can transfer only the configuration data.

Please let me know if I can use the Configuration Migration Tool to transfer actual data between instances.
