Another option for migration would be to do it during `start_subgraph_deployment`: if the `data_sources` table does not exist yet, create it and populate it from the current table. It might...

That's why I suggested to do it in `start_subgraph_deployment` since you know indexing isn't happening at that point. Yes, it will slow down startup; you are right that it'll be...
