Asp.net MVC routing for old aspx Url

We used to have some webforms setup that allowed us to edit jobs. External applications would access them using a URL like this:

http://server/EditJob.aspx?JobID=1235

having replaced the webforms with MVC the new URL is

http://server/MVC/Jobs/Edit/1235 

I would like calls to the former Url to be routed to the new URl as changing the clients is not possible. How can I achieve this?

I tried:

public static void RegisterRoutes(RouteCollection routes)
    {
        routes.MapRoute(name: "Job Link", url: "EditJob.aspx?JobID ={JobID}", defaults: new { area = "MVC", controller = "Jobs", action = "Edit" });

        routes.MapRoute(name: "Default", url: "{controller}/{action}/{id}", defaults: new { area = "MVC", controller = "Jobs", action = "Index", id = UrlParameter.Optional });
    }

But this gives a (System.ArgumentException: 'The route URL cannot start with a '/' or '~' character and it cannot contain a '?' character.'

So, can I do this using routing or should I recreate the old webforms as redirections to the new pages.

thanks

Update

Thanks to all you clever people I have discovered the wonderful world of IIS URL rewriting which seems to do exactly what I need.

I now have this rule inplace which is close to what I want:

   <rewrite>
  <rules>
    <rule name="Jobs page redirect" stopProcessing="true">
      <match url="EditJob.aspx" />
      <conditions>
        <add input="{QUERY_STRING}" pattern="JobID=(\d+)" />
      </conditions>
      <action type="Redirect" redirectType="" url="MVC/Jobs/Edit/{C:1}" appendQueryString="false" />
    </rule>
  </rules>
</rewrite>

But this redirects to:

 /MVC/Jobs/Edit/1235?JobID=1235

It would seem appendQueryString="false" doesn't work or am I missing something ?
