Content Delivery API - get numeric node ID

Questions
1

Hi everyone. I have some legacy data from V7 migrated to V13 that requires using old int node ID and I’d like to access it using the Content Delivery API.

However, can’t see it anywhere so I presume this can’t be done using the fields query and requires building a custom selector? Alternatively I could copy it to a custom property but I’d rather stop bloating the database.

Thanks for any pointers.

Can you explain a bit more about why you still have the v7 node id’s in your migrated data? The node id’s would have changed when you migrated but the keys may have remained the same depending on how you migrated you content.
