title: Do we require to do DML commands like insert in liquibase scripts of Corda state schema during migration from v1 to v2?
body: <p>Imagine I have added a new field called <strong>token</strong> in my <strong>CarV2</strong> State (version 2) &amp; suppose token's value populated should be <strong>existing</strong> field value = <strong>carNo</strong>+10.</p>
  <p>My thought process, is in liquibase schema script for version2 of CarV2 State, we just need to add a new column &amp; the data that needs to be populated in schema table will be handled in State Migration transaction inside Corda (means new state in migration txn of CarStateV2 can be created with this logic).</p>
  <p>Is that correct?
  Or should I need to add a DML operation command after the column addition changeset in liquibase script of version 2 itself for this (carNo+10) logic?</p>
