Migrating from earlier Versions of DataSync
Starting with version 14.5, CONNX DataSync is now a REST/Web server and can be accessed from any machine on the network via a browser interface. The stand alone version of DataSync has been deprecated but will still be shipped with CONNX as DataSync Classic.
Below are some points for consideration when upgrading from previous versions of DataSync Classic.
DataSync uses a migration utility to help upgrade the CONNXSTORE database to include necessary changes to the database. A program called "DatapumpUpgrade" is ran during the install to perform this task. In certain cases (when upgrading from CONNX 8.8, 8.9, and 9.0 SP1), the upgrade cannot work because the CDD must first be saved in the CONNX 11 (and later) format. The upgrade will succeed when the necessary actions listed in the table below are completed.
The following table displays actions that should be taken when upgrading to CONNX DataSync 14.5 and above:

Migration from CONNX VERSION | ACTION
8.8, 8.9, and 9.0 SP1 | Save the CDD in the current format by opening the CONNX Data Dictionary and re-saving it. Re-create DataSync schedules (necessary because of third-party control changes)
9.0 SP2 to 10.5 build 8331 | Re-create DataSync schedules (necessary because of third-party control changes)
11.0 to 14.0 | The previous native Windows version of the GUI has been deprecated and is available on the Windows Start menu as DataSync Classic. DataSync now provides a REST interface which is accessed from a browser. When the DataSync REST Server first starts, it will use the CDD that was in use by the previous version of DataSync. Any new CDDs activated with the REST server will be located in the connx32\datasync\cdd folder.
