bool
ValidatedSnapshotCleanup(
    xref:Chainstate.adoc[Chainstate]& validated_cs,
    xref:Chainstate.adoc[Chainstate]& unvalidated_cs);
----

== Description

If the cleanup succeeds, the caller will need to ensure chainstates are reinitialized, since ResetChainstates() will be called before leveldb directories are moved or deleted.

== Return Value

true if the cleanup completed successfully.
