Is it possible to migrate Memcached cluster data to Redis?

I have searched Google and SO and surprisingly haven't been able to find a very good answer to this.

Basically, I want to know if there is any sort of method or best practice for migrating cache data from a Memcached cluster into a Redis cluster. Are there are any tools or tricks to help with this process?

If it's not possible, is there any recommendation for how to handle this? I assume that pointing to a new cache that hasn't been pre-warmed will cause some application slowness, I'm just wondering if there are any workaround for this, assuming a migration of the Memcache data isn't possible.
