Branch organization: upgrade-v1 and massive-migrations

[krlosMata]

• feature/upgrade-v1
  • contains all the necessary code that implements new features in rollup v1
• feature/massive-migrations
  • contains code to perform massive-migrations

I think after we have everytihng coded for upgrade-v1, we need to rebase feature/massive-migrations into feature/upgrade-v1 and adpat it. Afterward, we can continue code masisve-migration to feature/massive-migration branch
