Elasticache

Deploy a test redis replication group and then in-place migrate to Valkey

Migration steps (takes around 17m):

Backup existing instance. Note the version and parameter group
In the example resource below, change apply-immediately, engine, engine-version, and parameter group.

When redis was initially deployed:

primary_endpoint = "lab-cache001.rw4ynm.ng.0001.ape1.cache.amazonaws.com" reader_endpoint = "lab-cache001-ro.rw4ynm.ng.0001.ape1.cache.amazonaws.com"

After in-place migration to Valkey:

primary_endpoint = "lab-cache001.rw4ynm.ng.0001.ape1.cache.amazonaws.com" reader_endpoint = "lab-cache001-ro.rw4ynm.ng.0001.ape1.cache.amazonaws.com"

Fallback

Simply reverting the code below will result in a replacement of the replication group. Meaning fallback is not supported. One will need to deploy a new instance and restore from backup
