Many existing cPanel/Plesk users have already moved to using a secondary database server (RDS being a dominant one). There was a lot of requests from the cPanel user community to enable RDS support to separate the DB from the PHP/HTTP layer, and use memcache or that DB Layer cache at AWS (Elasticache?) in between.
In these scenarios, the database config file has an external hostname for the DB access (not "localhost" or "127.0.0.whatever")
Reasons why we'd want the existing RDS as-is:
- Separate RDS means we can up/downscale that instance without modifying the main container.
- We've already paid for a 3 yr savings plan commitment for the RDS instance, and want to keep it.
- Why not? Snapshot backups at cloud level is reliable, less headache.
So in these cases, migrating over the PHP/DNS configurations is enough, and simply skip the MySQL import.
This would be a total waste anyway, as all of our PHP apps have an external RDS address configured, so the imported MySQL would not even be used/accessed unless we change the config.php file of each website.
