Hello,
At Flink Forward I learnt that Fink V1 state could not be migrated to V2. I 
think this would be a big migration inhibitor for current Flink users, as they 
would need to throw away their existing state. As such I think this is a 
critical possible blocking issue. Prior to Flink 2 going out, I think this 
needs to be looked at in case we need to amend the v2 state in some way to 
facilitate easier  migration.

Is this a task that is already in hand in the community? If not, I am happy to 
contribute this or be involved with the contribution – but would need guidance 
from the Flink PMCs on the approach,
      Kind regards, David.
