You are a SharePoint architect for Contoso, Ltd. Contoso has a SharePoint 2010 farm that contains four
site collections.
Each site collection has its own content database. Contoso is upgrading the SharePoint 2010 farm to
SharePoint 2013. You create a SharePoint 2013 test farm to test the upgrade process.
The SharePoint migration team reports the content database upgrade failed with the following errors:
 ERROR Database [ContentDatabase] contains a site (Id = [identifier], url =
[http://sitecolIectiona]) that is not found in the site map.
 Feature upgrade incomplete for Feature ‘ContosoCustomSite’ (Id: ‘Feature GUID’) in site
‘http://sitecollectionb’. Exception: A duplicate content type name “Customer” was found.
 ERROR Found a missing feature Id = [Feature Identifier]
You need to resolve the issues.
Which three actions should you perform? Each correct answer presents part of the solution.

A.
In the SharePoint 2010 farm, remove orphan objects from the content database and restart the
upgrade process.

B.
Extract the solution packages from the SharePoint 2010 farm by using the Get-SPSolution Windows
PowerShell cmdlet and install to the SharePoint 2013 farm. Run the Test-SPContentDatabase Windows
PowerShell cmdlet to confirm if the upgrade errors are fixed.

C.
Use the SharePoint Designer to delete the Customer content type from the site collection named
http://sitecollectionb, and then restart the upgrade process.

D.
Delete the site with the site definition Id = [identifier].

E.
Open the site collection named http://sitecolIectionb from the SharePoint 2010 farm and rename the
Customer content type and then restart the upgrade process.
