Migrating into CSDM identifying table dependencies
CSDM Migration CI's from Custom/Nonconforming Tables
What if you already have CSDM related data but not in the recommended tables. How do you migrate from a nonconforming use into the CSDM. That process takes several steps but the most important step is identifying any dependencies you may have created on your nonconforming table.
Attached is a script to use in your environment and instructions on how to run/utilize it. The results of this script will identify referenced dependencies such as Reports, UI Scripts, Business Rules, and other references for a specified table (editable in the script).
The results of this script help identify the level-of-effort (LOE) for migrating nonconforming CI's into the proper table of the CSDM.
Good luck and enjoy.
