I am shutting down a #Wikibase of mine and migrating whatever worthwhile content it has to #Wikidata. To facilitate this I wrote a Python script that feeds me each item in my Wikibase, one by one, and lets me decide whether to keep (i.e. transfer to Wikidata) or delete (or defer).

No changes are made on wiki. Rather, the information is tracked in a database I set up. Once I am done, I have a dataset I can work through. It makes the process significantly more efficient.
