DataSync uses a migration utility to help upgrade the CONNXSTORE database to include necessary changes to the database. A program called "DatapumpUpgrade" is run 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 matrix displays actions that should be taken when upgrading to CONNX 12:

 

CONNX VERSION	ACTION
8.8, 8.9, and 9.0 SP1	Save the CDD in the new CONNX 11 (and later) 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)
