Upgrading IIS 4 to IIS 6

I have a question regarding upgrading an NT4 web server with IIS 4 to Windows
Server 2003 and IIS 6. What do I need to take into consideration when
performing the upgrade. Since I am doing an in place upgrade on the same
machine I don't need to use the IIS migration tool. Are there any
fundamental differences between IIS 4 and IIS 6 that will block access to my
website? Is anyone else in the same situation or has completed this upgrade?

Not really. Do you use CDONTS? It's become obsolete and you need to switch
to CDO. Also make sure it doesn't default to IIS5 compatibility mode.

I dont think we are using CDONTS, we do use an ASPemail program that is part
of our Liberium Helpdesk software. As for the IIS5 compatibility mode this
sounds like a check box that I can look for during the installation. It
sounds like I should just install the OS upgrade and it will upgrade to IIS6
for me with no problems. Is it really that easy? I know I will need some
driver updates for this box which I can get from Dell and I will probably
need to uninstall Eeye's Secure IIS v2.11 but other than that it sounds i'm
on track. My worry is that i will get a bunch of forbidden errors or that
users wont be able to visit our website due to some permission problem. Any
Ideas?

Replicate your current live installation on a test box, then do the W2K3
upgrade there first. Your in-place upgrade might go okay, but then again it
might not. You'll want to work things on the test box so the live upgrade is
predictable.

Hello,

In general, you would not have any problems doing an upgrade.

But it is hard to tell for a specific server if there will be any problems,
without knowing what is used on the server. Before you upgrade, check all
third-party components that you are using, so they are compatible with IIS
6.0.

If it is possible for you, i would recommend you to install Windows Server
2003 on a separate machine (or a virtual machine if you have such software),
to check the website before upgrading. Doing that you will know if it will
work or not.

I can also recommend you to read thru Chapter 5 in Part 1 of the IIS 6.0
Resource Kit:
http://www.microsoft.com/downloads/details.aspx?FamilyID=80a1b6e6-829e-49b7-8c02-333d9c148e69&DisplayLang=en

That chapter has some very good information.

Good point.
