We use ADO with SAS 9.4 for change management purposes using the integrated Git and pipeline functionality. Only SAS program files are controlled this way however along with non-SAS reference data.
I don't use SAS DI, but my understanding is DI jobs are stored in SAS metadata. The only way to get these into ADO would be via exported packages unless there is some other API I'm not aware of.
The SAS Users Group for Administrators (SUGA) is open to all SAS administrators and architects who install, update, manage or maintain a SAS deployment.
