    Description

      With the introduction of a new config.placementHistory collection into the sharding catalog, the FCV upgrade process will need to take the appropriate steps to ensure that its content will be consistent.

      More specifically, the config server will have to generate a placement entry for each existing namespace (database/collection) based on a snapshot of config.databases, config.collections and config.chunks.
