I have a MOSS 2007 development vm. Recently I performed an attach upgrade to another SharePoint 2010 development vm. Everything works fine in the SharePoint 2010 development vm. I faced HTTP 404 error when I create new site collection within the migrated web application in SharePoint 2010 development vm. Anyone have idea on this? To be specific the HTTP 404 error happened when I browser to the url of the newly created site collection, the migrated site and site collection from MOSS 2007 are working fine.

Hi, sounds like a SharePoint 2010 issue and not a pre-SharePoint 2010 issue where you posted this question. Please post the question in a SharePoint 2010 forum: SharePoint 2010 - General Questions and Answers http://social.technet.microsoft.com/Forums/en-US/sharepoint2010general/threads SharePoint 2010 - Setup, Upgrade,Administration and Operation http://social.technet.microsoft.com/Forums/en-US/sharepoint2010setup/threads SharePoint 2010 - Using SharePoint Designer, Infopath, and other customization http://social.technet.microsoft.com/Forums/en-US/sharepoint2010customization/threads SharePoint 2010 - Using Visual Studio with SharePoint and other programming http://social.technet.microsoft.com/Forums/en-US/sharepoint2010programming/threads Dirk Van den Berghe

If my understanding is correct you attached a MOSS 2007 content DB to a SharePoint 2010 farm and did an upgrade. Also you are able to access the upgraded web application by browsing to it. - Are you facing this issue while using any template to create new site collection or is it with any one template? - Did you run the pre-requisite stsadm and powershell commands before doing a db attach? - did you do a visual upgrade on this new web application?

Hi Manoj V, - Are you facing this issue while using any template to create new site collection or is it with any one template? I am creating new site collection with built-in team site template - Did you run the pre-requisite stsadm and powershell commands before doing a db attach? yes, it does not show any suspicious issue (run test-spcontentdatabase on power shell) - did you do a visual upgrade on this new web application? no visual upgrade perform and i also notice the visual upgrade link in the settings page is missing.

please do not answer SharePoint 2010 questions here. Ask the question in a SharePoint 2010 forum instead Refer to http://social.technet.microsoft.com/Forums/en-US/sharepointadmin/thread/9d30a32d-324d-4300-9fdf-26cdef50b278 Dirk Van den Berghe

For the sake of people who may face this problem. I have perform visual upgrade and new created site collection is working fine.
