Re: Can I change a Program's Cannel from Tradeshow to Roadshow?
If you already have Members in the Program, you will not be allowed to change the Channel. Tradeshow and Roadshow (in default) have different Statuses, which will also be a reason you aren't allowed to change the CHannel.
You can try to do this by removing all Members (or exporting them by Status first).
For instance, add each status group to a static list in the Program
Remove all members from the Program
Remove all Status Changes in the Program
Remove all Status reference to this Program / inside Program
Change Channel - you may also have to delete the SFDC Campaign and create a new one
Add back the Program Statuses
Take your Static List and then select all, and do Change Status with the new Status you want these people to have.
