We are starting to consider Changeman as well. It is interesting because the ADSO code is stored in IDMS. Storing it additionally in Changeman seems workable since the Changeman jobs can be coded to use the MODIFY verb - which would essentially replace the objects in ADS.
I am afraid that configuring changeman for all the scenarios may be pretty complex. Dialogs will need generates, newcopy, etc where simpler objects like Modules and Tables will need fewer steps.
I wonder if anyone is already using Changeman with IDMS ADS?
