What happens to the IDs automatically assigned in the mysql databases when the 2 blogs are merged?

I’ve been studying the data in the mysql databases to be merged, and obviously many records in both databases have the same ID, beginning with 1. And there are other data fields in the database that use this ID# as well, for example https://www.domain.com/?p=3

Does the Import function anticipate that the data being imported might have the same id and automatically update these new records with new ids?
