Merging two items

Is there a module or a workflow that merges two IDs?

The requirements: I transfer two IDs and determine which should be kept and which should be deleted.

All connections of the two IDs are redirected to the one to be kept, the other ID is deleted.

Preferably, this would also work in batch mode, e.g. via a CSV.

Is there a module or a working workflow?

I know that I can also choose revise or update via the batch CSV import, but then I also have to import all dcterms:creator, for example, not just the one to be merged. This increases the effort and merging is actually a standard operation.
