We are in the process of restructuring our instance to split out a highly used channel into more specific sub-channels for more accurate reporting. We are rebuilding ~250 programs but want to mark all of the successes in the old programs as successes in the new programs with their historic success date. We can export all of the contact records with their success dates in each program via RCE and can easily say what each of their new successes would be in each new program.
Old Program Name
Old Program Success Date
New Program Name
New Program Status
Is it possible (perhaps via API), to import these records in mass into the new programs and assign them success with the historic date?
