Hi everyone
In 2.25 we will change the default MergeMode from MERGE to REPLACE (for metadata imports), this is being done because of the somewhat undefined characteristics of the MERGE mode (what is merged, and what is not… depends on the internal Java implementation, primitives vs objects etc)
Hopefully this should not cause any issues, but if you foresee any issues with your scripts or third party apps you can already today make it future safe by setting the merge mode explicit for imports (mergeMode=MERGE)
