If the logged-in user has the “Insert System Field Values for Chatter Feeds” user permission, the create field property is available on CreatedBy and CreatedDate system fields for this object. This allows the logged-in user to set these fields to the original post author and creation date upon migration instead of accepting the system field value when migrated, which would be the logged-in user and the date the migration was performed, respectively. The fields can't be updated after migration.
You can't query FeedLike records directly. They can only be queried via the entity feed, such as AccountFeed.
