Upgrading the
current Internet Information Service to IIS 7 possible, but you should meet be
two pre requisites mentioned below:
·
Source
operating system must be Windows Server 2003 Service Pack 1 or greater.
·
Current
IIS version should be IIS 6.0
·
For
Windows Vista, the source operating system must be Windows XP Service Pack 2 or
greater, and IIS 5.1
NOTE: Upgrading
from any version of Windows 2000, running IIS 5.0, to Windows Vista or Windows
Server 2008 running IIS 7.0 is not supported.
The upgrade
process takes place over three stages: detect & gather, installation, and
applying of settings. These steps only apply to operating system features and
settings; any file system content not created or owned by the operating system
will remain intact through the upgrade process.
What this means is that all web content present on the original
operating system will be present after the upgrade.
Detect
& Gather
During the
operating system upgrade to Windows Vista or Windows Server 2008, IIS detection
components are run on the existing operating system before the actual upgrade
begins. If IIS is detected on the existing Windows operating system, all
metabase and IIS state information will be gathered and persisted. The
information gathered is persisted in a the IIS7_Gather.log file located in the %windir%

Installation
The installation
phase consists of installing the Windows Vista or Windows Server 2008 operating
system, and then installing any optional features (such as IIS) if they were
detected on the original operating system. The choice of which IIS 7.0 updates
to install is based on the IIS state information gathered from the original
operating system.
Applying
Settings
After the
operating system installation and optional feature installations have
completed, the state information gathered from the original operating system is
applied. This is when the IIS metabase
settings from the original IIS installation are translated and updated into the
new IIS 7.0 config
store, ApplicationHost.config.
OCList.exe
Oclist.exe lists
all the packages to use with ocsetup.exe to add/remove a role or feature. This
also tells you if something is not installed on the server.
OCSetup.exe
Windows optional
components are parts of the Windows operating system that can be individually
added, removed, enabled, or disabled. You can use the Ocsetup.exe tool at the
command prompt to install or to remove Windows Vista optional components. You
must have administrative credentials to run the Ocsetup.exe tool.
