My team is working on a fairly large site that will be slowly transitioning (finally) into a mobile-optimized/responsive site. Since it is impossible to convert every page at once, there will be some mobile-optimized pages linking to non-optimized pages for a while. So the team is nervous about what the user expectation will be like going from a mobile optimized page to a non-optimized page.
Are there any examples on how this can be handled best with minimum user confusion? I am sure we are not the first team to have this problem but could not find an example of how a site gradually goes responsive.
