Migrations `dryRun` on multiple samples
When I run a migration in dry mode it executes on only one single document, which sometimes is skipped because it's not the instance of a document that needs to be migrated, which makes it hard to test the migration. Any suggestions?

Thank you!
1. It does a bunch but only logs one. Maybe drop a log in the migration itself off before/after? You can also pass the cursor in to start the next batch.
Good call that it could print the first one that differs.
2. I have a new version in the works where you can pass in a custom range to the migration so it doesn’t have to walk the whole table. Like q=> q.withIndex(
that would be great! Thanks Ian!
Could you validate
convex-helpers@0.1.59-alpha.0 ? It should print the first difference. The new version is a Component, so you'll have to wait for (2), but there's a beta version I'll DM you
