SharePoint 2007 to 2010 Migration Run pre-upgrade checker
You can use the pre-upgrade checker to report on the status of your environment and SharePoint sites before you upgrade to Microsoft SharePoint Server 2010. We highly recommend that the server administrator run the pre-upgrade checker and resolve as many problems as possible before scheduling the upgrade.
Note :
1. You might need to run the pre-upgrade checker more than once. For example, if you run the tool to evaluate your server farm but do not perform the upgrade for a few weeks, you can run the tool again just before you perform the upgrade to scan any new sites and to ensure that no additional issues have appeared in the meantime.
2. One frequent cause of failures during upgrade is that the environment is missing customized features, solutions, or other elements. Be sure that any custom elements you need are installed on your front-end Web servers before you begin the upgrade process. You can use the pre-upgrade checker — and, for a database attach upgrade, the test-spcontentdatabase Windows PowerShell cmdlet — to identify any custom elements that your sites might be using. For more information, see Identify and install customizations in the article "Use a trial upgrade to find potential issues."

About the pre-upgrade checker report
The pre-upgrade checker reports information about the status of your environment and the SharePoint sites in that environment, including:- Upgrade readiness and supported paths Returns
a list of all servers and components in the farm and information about
whether the servers meet requirements for upgrading.
- Alternate access mapping settings Returns a list of the alternate access mapping URLs that are being used in the farm.
- Installed elements
Returns a list of all site definitions, site templates, features,
and language packs that are installed in the farm. You need to know
which site templates have been installed or used so that you can verify
that they are available after an upgrade or database attach. You also
need to know which elements have been customized so you can verify the
customizations again after the upgrade. For example, you need to know
whether a site depends on a language pack for Office SharePoint Server
2007 that does not exist yet for SharePoint Server 2010, so you can plan
how to handle that site during upgrade.
- Unsupported customizations Reports
whether any server-side customizations that are not supported (such as
database schema modifications) exist in the farm.
- Orphaned objects Lists
any database or site orphans in the farm. Objects such as list items,
lists, documents, Web sites, and site collections can become orphaned —
that is, the objects exist but are not associated with a particular
site. Because orphaned objects do not work in the previous version, they
won’t work after the upgrade. If you perform an in-place upgrade, the
orphaned items will still exist, but will not work. We recommend that
you repair any orphaned objects before upgrading.
Tip Members of the Administrators group on the front-end Web servers can repair orphaned items before the upgrade by following the steps in Knowledge Base article 918744, Description of a new command-line operation that you can use to repair content databases in Windows SharePoint Services (http://go.microsoft.com/fwlink/p/?linkid=69958&clcid=0x409).
- Valid configuration settings Reports
any missing or invalid configuration settings (such as a missing
Web.config file, invalid host names, or invalid service accounts) that
exist in the farm.
- Database requirements Reports
whether the databases meet the requirements for upgrade — for example,
databases are set to read/write, and any databases and site collections
that are stored in the Windows Internal Database are not larger than
4 GB.
- Whether to perform an in-place upgrade or a database attach upgrade.
Determine upgrade approach (SharePoint Server 2010) provides information to help you decide which type of upgrade to perform. It is important to consider the report generated by the pre-upgrade checker when you make this decision. If your servers do not meet the requirements for in-place upgrade, you need to consider performing a database attach upgrade.
- Whether to upgrade some or all site collections that contain customized sites.
- Which
sites need to have customizations reapplied or redone after upgrade and
therefore might take longer than others in the review stage.
