# NAME

Xapian::DatabaseVersionError - DatabaseVersionError indicates that a database is in an unsupported format.

# DESCRIPTION

    From time to time, new versions of Xapian will require the database format
    to be changed, to allow new information to be stored or new optimisations
    to be performed.  Backwards compatibility will sometimes be maintained, so
    that new versions of Xapian can open old databases, but in some cases
    Xapian will be unable to open a database because it is in too old (or new)
    a format.  This can be resolved either be upgrading or downgrading the
    version of Xapian in use, or by rebuilding the database from scratch with
    the current version of Xapian.
