Is this SPS or WSS? If it's SPS, the top navigation  shows the defined top  level
areas. A quick and dirty solution for linking back  to your existing intranet  is
to create all the Areas to get the navigation, and in the page for each area
that needs to point  back (call this a placeholder if you will), insert a Content
Editor web part. In that content  editor, add  this - replacing "the_old_url"
with the full url to the old site  location:

------------------------------------------
<script language="javascript">
<!--
//redirect to the old site
window.location.href="the_old_url";
-->
</script>
Click <a href="the_old_url">here</a> if you are not automatically redirected.
-------------------------------------------

When you are ready to migrate, just delete the placeholder Area and create the
migrated one in it's place.

Thank you! I'm still really, really, new to SPS, but
this worked (with a minor modfication). I also had to
use FrontPage to delete the section  after my test, but
it does work. :o)

I plan to create an area called "HumanResources2" with
a display name of "HumanResources". HumanResources2
will have the redirect in it. I'll create another area
called "HumanResources" but a display name of
"HumanResources1" and have it hidden while we are
developing it. When I'm ready to make that particular
are live, I'll just delete the one with the redirect
and rename the display name of the one I've been
developing.
