Does someone encounter some weird behavior with updating ReplicationGroup ElasticCache state ? I’m trying to change my ReplicationGroup instance type from

cache.t3.small

to

cache.m5.large

. The pulumi preview works great, then the pulumi update succeed but when looking in AWS console, the instancetype is still

cache.t3.small

, and the replication instances aren’t in modifying state. Very weird… Thanks !

Hello @billowy-horse-79629, can you verify that you are looking in the AWS console at the exact resource as you applied the change to with Pulumi?

I do checking the exact resource. I’m sure about it as I have only ReplicationGroups that got created by Pulumi, no any drifted resources.
