Safely removing unused columns identified via dependency checks in Appian

Hello all,


I have come across certain columns of different tables which are not being used in anyway. To validate  this, I have done the following :

Check for CDT dependencies Check for record type dependencies Search for usage of the field/column globally in the application

Based on the above, it appears that these fields are not being referenced by anything.

But prior to deleting the columns, I wanted to get your feedback regarding the following:

Does the above process ensure that the columns can be deleted without causing any issues ? Is there anything else that needs to be checked prior to deleting such columns (Process Models, integration etc.) ? What is the best way to delete such columns in Appian ? Am I supposed to deprecate these columns prior to their deletion ?

Thanks
