SSPR URLs

Hi,

In FIM 2010 RTM, sometimes we configured the SSPR URLs as http://fimserver/passwordreset or /passwordregister.

In FIM R2, I see the SSPR guide points to http://passwordreset.company.com ...

Does this mean that the virtual directory /passwordreset example will not work with FIM 2010 R2 anymore and all the SSPR Portals have to be reinstalled (if we are migrating)?

thanks,

SK
