Migrate .Net 2.0 web apps from 32bit W2k3/IIS6.0 to 64bit w2k3/IIS6.0

Posted on 2010-01-08
Last Modified: 2013-12-14
I have to migrate from our existing server (Windows 2003/32bit/IIS 6.0) to a new server (Windows 2003/64bit/IIS 6.0). All of our web apps are developed in VS 2005 using C# code-behind. How difficult is this migration going to be and what should I look out for? Will our web apps work as they are as long as the x64 versions of the .net framework are installed? Please help as this is urgent.

    Your migration should be fairly seamless.  If you run into any problems you can run the worker processes in 32 bit mode and still run on a 64 bit OS.  Enabling this is simple:

    To enable IIS 6.0 to run 32-bit applications on 64-bit Windows
     Open a command prompt and navigate to the %systemdrive%\Inetpub\AdminScripts directory.
     Type the following command:

    cscript.exe adsutil.vbs set W3SVC/AppPools/Enable32BitAppOnWin64 true
     Press ENTER.

    I researched this before posting the question so I believe this is correct advice. Thanks for your help! Can I post other questions about this, if I have them, while performing the migration?
