CPQ pattern
What happens to Apex triggers on CPQ objects after migrating?
A trigger bound to an SBQQ__ object has no target once the data lives in Revenue Cloud objects. It does not error and it is not reported anywhere — it simply never fires again.
How it fails
This is the classic case: validation that silently stops validating, and field defaulting that silently stops defaulting, on records that look fine until somebody audits them.
What to do instead
Identify the equivalent Revenue Cloud object and reimplement, or fold the logic into a Pricing Procedure.
