Metadata is stored within a database for each of a plurality of objects in different frames associated with a structure descriptor (e.g., a container directory entry, etc.). The frames are part of a metadata page and each comprising an object and a header specifying a version identifier for the object and a size of the object. The structure descriptor initially is built for a first build identifier. Thereafter, upon the structure descriptor changing from the first build identifier to a second build identifier, at least one of the objects that require migration is identified. The identification is based on the version identifier for the object being different from the second build identifier. In response, the identified objects are migrated from their corresponding frame to a new frame. The new frame includes the objects and new headers that include a version identifier equal to the second build identifier.
