Replacing collection column by other collection column

[LaurentDELOBEL1]

I have one collection (Col1) with 3 columns (A,B,C) and a second collection (Col2) with 3 columns (D,E,F). I would like to replace the whole column B from Col1 by the whole column E from Col2. What would be the best way to do it ? Any suggestion will be appreciated.

You can do following : 1. Merge both collection with ""Merge Collection"" action of ""Utility - Collection Manipulation"" object. 2. Then Delete the required columns with action ""Delete Column"": of ""Utility - Collection Manipulation"" object.
