I think you misunderstood my statement.
{noformat}
Did you give manual ids to all operators (only then we guarantee that things can be restored)?
{noformat}

{noformat}
Arvid Heise No. No manual ids have not been give to any operators. Only in one section, we have given but the job name is same for both 1.9 and 1.10.2 version so, I think it should not matter. All are DataStream APIs, we are not using any Table APIs.
{noformat}

So let me quote the [https://ci.apache.org/projects/flink/flink-docs-stable/ops/state/savepoints.html#assigning-operator-ids|http://example.com]

{noformat}
It is highly recommended that you adjust your programs as described in this section in order to be able to upgrade your programs in the future. The main required change is to manually specify operator IDs via the uid(String) method. These IDs are used to scope the state of each operator.
{noformat}

I'm suspecting that the automatically generated IDs are incompatible between versions and they are not guaranteed to be stable.

So I propose to you to retry the migration with setting the uid before and after upgrade.

> We tried to save checkpoints for one of the flink job (1.9 version) and then import/restore the checkpoints in the newer flink version (1.11.2). The import/resume operation failed with the below error. Please note that both the jobs(i.e. one running in 1.9 and other in 1.11.2) are same binary with no code difference or introduction of new operators. Still we got the below issue.
> _Cannot map checkpoint/savepoint state for operator fbb4ef531e002f8fb3a2052db255adf5 to the new program, because the operator is not available in the new program._
