Redirecting Old Site to New Site Same Directory

I have other links that is going to come from other app owners that wants to stay within the old site and keep users there until they move the content over to the new site.is it something like this?

e.g.

[root@ve10:Active] config  b virtual bar list
virtual bar {
   snat automap
   pool foo
   destination 172.28.19.252:80
   ip protocol 6
   rules myrule
   profiles {
      http {}
      tcp {}
   }
}
[root@ve10:Active] config  b rule myrule list
rule myrule {
   when HTTP_REQUEST {
  if { [string tolower [HTTP::host]] equals "oldsite.com" } {
    set uri [string tolower [HTTP::uri]]
    if { $uri equals "/" } {
      HTTP::respond 302 noserver Location "https://landingpage.com"
    } elseif { not ($uri starts_with "/it/useradmin/") } {
      HTTP::respond 302 noserver Location "https://newsite.com[HTTP::uri]"
    }
  }
}
}
