Issue with rollback feature.

[pavankataria]

Create a third schema and add it to the relevant plans.
Migrating forward works correctly say from V2 -> V2_1_0, but when you want to test rolling back from V2_1_0 -> V2... it does the rollback but it also calls the rollback from V2 -> V1 which is incorrect so you're not able to test V2 rollback in isolation.
Can you update the code so that we can test rollbacks properly on what was intended?
