I'm bit green on MySQL upgrades, but my question has to do with single schemas (dbs). I have some hosted databases on a server using MySQL 5.1 Community, and I currently use mysqldump to back those databases up. When I go to restore them into the MySQL 5.7 server, do I need to run an upgrade on those databases to bring them "up to speed"?
The mysql_upgrade command seems to be related to all database within an instance, and I will be moving dbs one at a time into the server that has had dbs created from scratch there, as well as other dbs that have been moved to it from the previous version (5.1).
