Within a given instances of a configuration (exp. MyConfig version 1), all element classes, such as a geo region, IDs must be unique. However, origin IDs must be unique at the SCID/subscriber level. Therefore, when promoting a new configuration that contains an origin ID that overlaps with a previously deployed origin ID for a completely different configuration, it will fail. To ensure uniqueness at the SCID/subscriber level, we recommend using a convention, such as appending EPOCH time when generating the ID.
