    Description

      During startup, the featureCompatibilityVersion document is checked to ensure a valid FCV. However, it may be the case that the document was recently updated and this updated version needs to be recovered from the oplog through by replication recovery (as opposed to being able to recover it through WT journal recovery). If this occurs, this FCV validity check could fail even if the FCV had been set to a valid value.
