I have follow the steps to upgrade SHP2007 to SHP2010 using the database attach method. The content database was upadated successfully and attached to a new web application.
Here are my three problems so far. 1-The web application is not displaying but my old 2007 data is not showing. Is there any step that I have missed? There is no other database attach to the web application.
2-The other error I am gettig is when I run the test database command. Category : MissingWebPart Error : True UpgradeBlocking : False Message : WebPart class [f4b61a9b-a3d0-8d94-0eed-a84ee19b26c6] is referenced  times in the database [WSS_Content], but is not installed on the current farm. Please install any feature/solution which contains this web part. Remedy : One or more web parts are referenced in the database [WSS_Content], but are not installed on the current farm. Please install any f eature or solution which contains these web parts.
When I search in SQL by the id, is refering to a mysite webpart. WebUrl="mysite".
3-Visual upgrade is diasable, grayed out.
Any idea what I did or might be doing wrong?
I havent attached any other database. I am waiting to resolve this issues. At least I will like to be able to see my 2007 site running under 2010.
Any help will be very appreciated.
