The expression $version->isMigrated() of type null|boolean is loosely compared to false; this is ambiguous if the boolean can be false. You might want to explicitly use !== null instead.

            throw new CollectionException(
                'Invalid version specified: this collection only accepts deltas that are migrated.'
            );
