we upgraded our AWS RDS mysql instance from 5.5.42 to 53 and we applied the original parameter group to this instance.
However when I checked the rds instance's configuration details, the Parameter Group value remains "pending-reboot" even though I've manually rebooted the rds.
How do I fix this issue? Thanks!
Hi so I found a solution which is quite simple. I had to make a minor edit to the parameter group (any one of the many variables will do), and save the changes. After that I rebooted the rds instance and now the parameter group is in-sync.
