This feature involves the creation of two upgrade processes to add the column CONFIGURATION to fragment tables. These kinds of changes are considered minor schema version and that means that they are non-revertible due to our policy.

However technically is possible to come back to the previous code even when the changes in the database have already made. New columns shuldn't affect to the correct behaviour of the service or other layers.

For this reason, we are going to make this feature revertible generating micro schema version instead of the minor changes.
