Remove SP 2003 to install MOSS 2007

  Asked By: Weston    Date: Mar 28    Category: MOSS    Views: 1146

Has anyone had this problem.

I have a test server with SharePoint 2003 installed with a copy of our
production data. I want to do a gradual in place but I get an error

Setup is unable to proceed due to the following error(s): This product
cannot be installed on a computer with SharePoint Portal Server 2003
installed. Remove SharePoint Portal Server 2003 from this computer and
then install this product. Is this to be expected? It seems to go
against migrating current SP 2003 data to MOSS 2007.

What are you installing when you get the error? You say you are trying do
the upgrade on a single server, but you want to do a gradual upgrade. If you
do an in-place upgrade, which is upgrading 2003 to 2007 on a single box, it
will upgrade the entire install, not just parts of it. Are you installing
the binaries of 2007 when you get the error? Have you applied SP2 to your
current 2003 install  first?

.NET 3.0 and ASP.NET 2.0 need to be installed and activated first also.
Otherwise it assumes an upgrade isn't possible.

Tried to install  the binaries again and got the same error message.

I haven't messed with 2003 in a very long time, but stopping the web service
in SharePoint is not quite the same as stopping the Microsoft services from
the services mmc.

What do you mean by the web service in SharePoint? I thought that was
the microsoft services in MMC.
