Is there an established "best practice" for migrating default column formats between environments (i.e. from Dev to QA or from QA to Prod)? MIgrating individual analyses is easy, and migrating the updated repository is fine. But what about the default column formats (for example, Profit Margin % has a default data format of 1 decimal place with percentages)? The only way I can see to migrate those is to copy the the file with the name of the subject area (and no extension) from C:\<home>\user_projects\domains\bi\bidata\service_instances\ssi\metadata\content\catalog\root\system\metadata (that is the 12c folder), and paste it into the new environment. But that runs the risk of overwriting stuff that may have been added in the upstream environment.
What is the best practice in this area?
