Hi Nolan, It's hard to say exactly what's happening without looking at your instance specifically, but here's a few things that could be preventing a successful major version upgrade:
- The MySQL documentation for upgrades says "Upgrading to the latest release is recommended before upgrading to the next version. For example, upgrade to the latest MySQL 5.6 release before upgrading to MySQL 5.7." If there is a higher 5.6.x version available to upgrade, start there.
Before attempting a major version upgrade, AWS also recommends that the instance
- Be running in a current/recent generation instance class
- Have all RDS pending/available maintenance actions applied
Additionally, because a major version upgrade can be time-consuming and resource-consuming, we recommend that the instance be running in one of the larger instance sizes, to minimize downtime.
Should these tips not get the instance to the point where it can upgrade, I'd advise opening a support case for help specific to your instance.

What instance type are you using? If this is an old instance type and you're trying to upgrade, you may need to upgrade to a newer instance type to support the 5.7 upgrade.
