How do you force WeBlog to reorder blog posts into new folder structure?

Question

The base WeBlog config contains these nodes:

<event name="item:saved">
    <handler type="Sitecore.Sharedsource.Tasks.NewsMover, Sitecore.Sharedsource.NewsMover" method="OnItemSaved">
        <database>master</database>
        <templates hint="raw:AddTemplateConfiguration">
            <template id="Modules/WeBlog/BlogEntry" sort="Descending">
                <DateField>Entry Date</DateField>
                <YearTemplate formatString="yyyy">Common/Folder</YearTemplate>
                <MonthTemplate formatString="MMMM">Common/Folder</MonthTemplate>
                <!-- Uncomment the following line if you have too many posts per month (more than 100) -->
                <!--<DayTemplate formatString="dd">Common/Folder</DayTemplate>-->
            </template>
        </templates>
    </handler>
    <!-- Keep the post and comment handlers seperate to ensure comments are structured below posts and not within the same folder structure as posts -->
    <handler type="Sitecore.Sharedsource.Tasks.NewsMover, Sitecore.Sharedsource.NewsMover" method="OnItemSaved" use="comments">
        <database>master</database>
        <templates hint="raw:AddTemplateConfiguration">
            <template id="Modules/WeBlog/BlogComment" sort="Descending">
                <DateField>__created</DateField>
                <YearTemplate formatString="yyyy">Common/Folder</YearTemplate>
                <MonthTemplate formatString="MMMM">Common/Folder</MonthTemplate>
                <!-- Uncomment the following line if you have too many posts per month (more than 100) -->
                <!--<DayTemplate formatString="dd">Common/Folder</DayTemplate>-->
            </template>
        </templates>
    </handler>
    <handler type="Sitecore.Modules.WeBlog.Globalization.ItemAndPublishEventHandler, Sitecore.Modules.WeBlog" method="OnItemSaved"/>
</event>

If the line below is uncommented for BlogEntries, how do you force WeBlog to reorder the existing blog posts into the correct folders (now containing a day folder)?

<DayTemplate formatString="dd">Common/Folder</DayTemplate>

Currently using Sitecore 7.1 and WeBlog 5.3.
