Thread:Project:Support desk/Possible to change a Template and have it update already created pages?

We are looking at MediaWiki to replace our current technical documentation system. The feature that we are looking for, and I am not sure if it is possible or not, is to have a page layout/template that has all of the fields for each client. But, if we decide to make a change to the template in the future we would want the change to take place across all pages using that template. Is this possible? If so, how?

Thanks.
