As an Infrequent User, I want to see unread notifications even if I haven't logged in a long time, so that I am not suprised when I look at my notifications list and see notifications marked as "read" that I have not read.
This is the user story for migrating data from the Redis server to the Kask server.
Priority: must have

| Declined | None | T234295 Migration of old timestamps |
During discussions w/ @Catrope, we determined that the impact of timestamp misses were sufficiently minor as to not justify us spending the time to write, test, and debug a migration of data from Redis. What we will do instead: Deploy with a MultiWriteBagOStuff that wraps the new and old store (read-from-new, fallback-to-old, write-to-both). There will be some 90 days or more between this deployment and the decommission of Redis, during which time most active users will have seen-times seeded into the new store.
TL;DR We are declining this.
