Export Exchange 2007 Journal Rules and Import into Exchange 2013

Hi, 

I'm needing to export our Journal Rules from exchange 2007 and then import them into exchange 2013, this page "http://technet.microsoft.com/en-gb/library/ee633488%28v=exchg.141%29.aspx" says how it can be done, but i do not have the Export-Jou...... option in exchange 2007. 

Any help will be greatfull. 

Thanks

William
