Question

How are the existing processes affected when new columns are added to the CDT and View?

We will be adding columns and changing data types to the database but are not sure of the extent of the impact that it will have on our in-flight processes.

Has anyone done this before -- any advice?...

Hi Arun, 
Suppose you have CDT and it has 4 fields and there are 200 active instances runing on it. 
 
Now you added two more columns,untill you refer these two more columns in process instances all the active Instances will 
not fail. 
 
If you have redesigned the subprocess and used the newly added columns, In this case the new subprocess always use the 
new version of the CDT and Existing Instances still continue to work. 
 
If you have used any where in SAIL, then the sail code will fails in the active process instances since the SAIL updates directly take impact.
