# Check dump file version (Linux/Unix) strings hr_12_2_compat.dmp | grep -i "version"
-- Generated by Oracle Data Pump (version 19.0.0.0.0)
The 19c expdp generates a dump file compatible with Oracle 12.2 by limiting metadata to features available in 12.2.
Even though both versions belong to the 12c/19c family, Oracle considers 19c as a higher version number. The dump file format and metadata structures evolve with each major release. Oracle 12.2 does not have the necessary internal logic to interpret new features, system objects, or XML schemas that may exist in a 19c dump file.
