Question - how best to change the parent of a historical value?

I need to change the parent from SELF.ARC to NEW.ARC
Can also values be copied from one database to another?

The parent can be changed online (in version 21.0.70 and newer, patches newer than 23.2.2024) via:

The values ​​are not copied. Only the configuration of the D2000 will change.
But you can export concr. table/tables and import it - example for PostgreSQL:
pg_dump.exe -U dba -F c -v -f my.dmp -n public -t “DT1234567” -t “DT1234560” “MyApp.Archiv”

pg_restore.exe -U dba -F c -v -d “New.Archiv” -n public -t “DT1234567” -t “DT1234560” my.dmp
