Source and target databases do not share a company id. Pass…

Error message

Source and target databases do not share a company id. Pass --company explicitly once both sides match.

What it means

Cross-database company resolution failure: the source and target databases share zero company ids, so there is no company whose history could be merged; the operator must make both sides contain the company first.

Solutions

1. Seed or create matching companies on both sides, then pass --company explicitly.
