A common pitiful when upgrading a Flink application with savepoints is that
no explicit UIDs have been assigned to the operators. You can amend that by
first adding UIDs to the job in 1.9.3 and create a savepoint with UIDs.
Then try upgrading again.

Hi,
I'm not aware of any breaking changes in the savepoint formats from 1.9.3 to
1.11.3.
Let's first try to rule out any obvious causes of this:
- Were any data types / classes that were used in state changed across the
restores? Remember that keys types are also written as part of state
snapshot
