@janmatzek Quick question on IDs: with --keep-original-ids, report migration now seems to use the raw legacy identifier directly and skip the usual report-specific ID prefix. Was that intentional? Just want to make sure we’re OK with the possible collision/behavior change here.

@Tomkess Yes, intentional, happens for both reports and pixel perfect dashboards. It has side effects when the prefixes are omitted, they are mentioned in the readme file.

This covers a specific customer use case where retaining the IDs is requested to keep some mapping consistent on customer side.
