Answer 1

You can now perform in-place upgrade from Aurora MyQSL from 5.6 to 5.7

Only a matter of invoking modify-db-cluster or modify-global-cluster (if you are using global clusters of course).

More in the docs (including how to do this using the AWS console).

Answer 2

To manage an update for a DB instance or DB cluster

Sign in to the AWS Management Console and open the Amazon RDS console at https://console.aws.amazon.com/rds/.

In the navigation pane, choose Instances to manage updates for a DB instance, or Clusters to manage updates for an Aurora DB cluster.

Select the checkbox for the DB instance or DB cluster that has a required update.

Choose Instance actions for a DB instance, or Actions for a DB cluster, and then choose one of the following:

• Upgrade now

• Upgrade at next window

Note: If you choose Upgrade at next window and later want to delay the update, you can select Defer upgrade.

Answer 3

According to this link, you cannot upgrade an in-place database, you will need to restore a snapshot of the existing database and change the engine version during that process. These restrictions appear to be only temporary and may be lifted at a later point to allow for in-place upgra

Answer 4

Easiest way is:

1. Take a manual snapshot first of Aurora MySQL 5.6 cluster.

2. Then, create a new Aurora MySQL 5.7 using that manual snapshot which was taken in step 1

3. Your credentials would be same as that of the older 5.6 cluster.

4. Verify if data is correct.

Answer 5

The comments above are true; there is still no in place upgrade for 5.6 to 5.7; the process is still pretty easy though;

1) Go to the RDS dashboard, in the left hand menu there is a menu item called 'Snapshots'; you can either click on this if you are ok using a recent snapshot; otherwise select your database & on the actions drop down & choose 'Take Snapshot'

2) In snapshots simply select your snapshot & choose 'Restore Snapshot' from the actions drop down; it will automatically duplicate a bunch of your previous settings. Its at this juncture you can select the new database engine of 5.7

All and all you should allow for at least a half an hour of downtime for the whole process. Probably a couple of hours to be on the safe side.
