datapump cannot migrate

in Database Utilities (MOSC) 4 commentsAnswered

I have 2 databases, 19c Standard edition 2, one on oracle linux 8 and one on oracle linux 9. Both use AL32UTF8 charset. Source uses a filesystem, target uses ASM and SEHA. Source is 19.17, target is 19.27.

I wanted to migrate data from one db to another one.

Source:

expdp \"/ as sysdba\" schemas=… exclude=statistics consistent=Y

Target:

impdp \"/ as sysdba\" schemas=…

Error message:

Processing object type SCHEMA_EXPORT/PACKAGE/PACKAGE_BODY
ORA-39346: data loss in character set conversion for object PACKAGE_BODY:"GMB"."JSONFLY"

How is it possible? Both databases use the same charset, and it is the same version (19c SE).
