Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I suspect this may not be possible for security reasons or something, but I must ask.

I'm in charge of a migration project involving around 50 intranet applications. This process will take time and as a proposed strategy I would like to migrate them one at a time, test, then go-live. However, I do not want the URL to change in order to preserve pre-existing links.

My proposed solution is to use a redirect on the old server for the specific app, then use the URL Rewrite module on the new server to make the URL look the same as the old server so the user would never know the difference and all links would still work.

Is this possible? If not, what is the best practice for achieving my goal? Thank you! :)

  • Goal: Move the web app without breaking pre-existing links to it.
  • Old Server: Windows Server 2003 with IIS 6
  • New Server: Windows Server 2008 R2 with IIS 7.5

I would be tempted to move all 50, setup and test, change DNS and go live. Seems easier to me but I suppose your sites might be quite complexed. –  boburob Oct 3 '12 at 22:12
@boburob They are unfortunately, but that may end up the best solution; I'm hoping not. They were all developed over the last decade or so and are all on different .NET versions, different VS versions, etc. and ZERO documentation. It's mind numbing. :( –  Chiramisu Oct 3 '12 at 22:16
