    <para>
        To upgrade to a later version of Noisemap, simply perform a <link
        target='#WC_InstallInstructions_id'>normal installation</link>,
        noting these points.

            <para>
                If any Noisemap programs (BaseOps, NMap, NMPlot, etc.) are running,
                close them before performing the upgrade.

                Install Noisemap in the same directory that it was previously
                installed in.

                The <filetext>Flight01.dat</filetext> and <filetext>Static01.dat</filetext>
                files in the <filetext>Noisemap\NMap</filetext> directory will
                be overwritten during the upgrade process. If you have modified
                these files, you should make copies of them before upgrading Noisemap.

    <para>
        All &app_name; configuration information is stored in the file
        <filetext>&app_name;.cfg</filetext>. This file will not be overwritten
        when you install later versions of Noisemap. Therefore, your configuration
        will be preserved.
