MySQL RDS - do the SSL certificate updates need to be applied in a specific order in and primary/replica configuration

0

I need to update SSL certificates on MySQL RDS instances that are linked in a Primary/replica configuration. If I update the replica first, will this cause issues with the replication and the break the connection between the two RDS instances?

The instances are hosted in different availabiiity zones within the same region.

Regards,

Ross

Hello Ross, as mentioned in the AWS blog below the CA Certificate update must be executed on each of the read replicas. These updates can happen among the Primary and Read Replica DB instances in any particular order.
