Upgrade from NAV 2009 to NAV 2013

Hi Everyone,

We are going to upgrade from NAV 2009 SP1 to NAV 2013 however we have a web service set up with an Internet Information Server IIS. Now to my knowledge NAV 2013 offers publishing of objects through Sharepoint.

My question is whether our current infrastructure using IIS rather than sharepoint will have difficulties when we create a web service through IIS and publish.

Any documents/articles are welcome.

Thanks.
