[google-cloud-sql-discuss] Re: Reduce migration downtime

Hello Markus, 

You are right: replicas are always the same generation (First Generation or Second Generation) as the master instance, as detailed on the "Requirements and Tips for Configuring Replication" documentation page.

The need to dump first is justified by the time-related differences in database content, as one needs to import data for a certain moment in time. More information on the migration process to second-generation can be gathered from the "Migrating an Instance to Second Generation" page.
