ORA-64219: invalid LOB locator encountered

[cesardba]

I’m trying to migrate a table that contains several LOBs, with approximately 1 TB of data. The source is Oracle 11g and the target is Oracle 19c. Unfortunately, I’m encountering the errors below.

I tested with all the updated drivers. When I load data between databases of the same version — for example, from 19c to 19c — it works correctly. However, when I try to load from 11g to 19c or 12c to 19c, the problem occurs. I believe the issue might be related to the replica database configuration. Could you please help me investigate this?
