I've taken my moss 2007 db backup and used attach method to upgrade on sharepoint 2010. Upgrade went successful and users can see the sites and can navigate also. Interface is same as moss 2007. I am facing two problems on migrated portal.
I can only Visual upgrade HOME site and on other sites when i click on VISUAL UPGRADE i see "File not found" error.
Some of the lists which contains pdf documents, word files and excel files when portal contributor who has rights to upload, edit and delete permissions when user clicks on any document to perform operations it says "List does not exist The page you selected contains a list that does not exist. It may have been deleted by another user." But when I tried creating a new list the user was able to perform upload, delete etc..strange..but not working with existing lists.
How to resolve the above mentioned issues...I am new to moss so kindly guide by giving a hint where to find options to fix it. Would appreciate guidance like for example go to Site Settings-> Visual Upgrade ..etc
