I am doing a Gradual Upgrade of WSS 2.0 to WSS 3.0. There were 3 sites in the WSS 2.0 instalation. In the WSS 3.0 Administration console I have upgraded the first site and that seems to be OK. I am now trying to Upgrade the 2nd site. However after entering all the relevant details I get the following message. "The IIS Web Site you have selected is in use by SharePoint. You must select another port or hostname" This site is on a different IP address from the first site. Has anyone any idea what is happening.
Also the 3rd site from the original WSS 2.0 instalation does not appear in the WSS 3.0 administration console at all.
I can still access it OK as a WSS 2.0 instalation.
