The IIS Web Site you have selected is in use by SharePoint.  You must select another port or hostname

Hi

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.

Can anyone help please.

Thank you.

Probably a few ways to handle this, but why not backup and restore and just create new clean web apps and then restore your WSS 2.0 content databases into your WSS 3.0 farm?
If IIS is an issue, make your full backups, drop and remove them from the 2.0 configuration entirely, and then setup the 3.0 exactly how you want it.

Hi this is the first time I have upgraded a SharePoint site.

Could you elaborate a little on the details of what you are suggesting.

If I create a new Site (Web app) in the WSS 3.0 Admin console will it ask me to iether create a new Content Database or attach an existing database. (Which would be the restored WSS 2.0 database).
When the Database is attached WSS 3.0 would then upgrade the database to 3.0?

Is this what you mean.  If not could you explain in a little more detail.  Presumably I would need to give the new Sharepoint site a new name and IP Address untill I can turn off the version 2.0 site.  What about permissions.  Would the permisions from the 2.0 install be upgraded?

Thank you for your help.

If still looking for solution, I'll give some more info. When you go to create a new web application, it will ask you to type in the name of a content database. You can just type in a specific name (temporary, as you will delete this database after).
Once it creates it, from Central Administration > Application Management > Content Databases, you can then delete this empty database.
You can then attach this other database that you want to upgrade. You may need to do it from STSADM.

Thank you.
I have been working on this issue with someone from Microsoft.  And it has been decided that the best way to upgrade my sites is going to be to put WSS 3.0 on a new server. and do a database migration.
This is the only way I can keep both a WSS 2.0 instalation and a WSS 3.0 instalation.  Your information though does help to clarify what I am doing.  Thank you.
