There are multiple ways to migrate data from ElasticCache to Redis, each with its own set of considerations and potential drawbacks. The primary decision point is whether a flush of all Redis data is tolerable, which can result in slow performance while data is rehydrated. If not, offline or live data migration options are available, with the latter requiring more operational complexity but offering no downtime or lost data. Understanding the tradeoffs and choosing the right approach is crucial to a successful migration.
