    Hi,

    We are palnning to upgrade a 3 node a/a/p clustered sql server 2005 to 2008 using in-place upgrade and I'm going through the upgrade documnet 'SQL2008UpgradeTechnicalReferenceGuide.docx' and SCC (System Configuration Checker) checks the following:

    •The destination computer must be connected to the Internet while the .NET Framework security check validates a certificate.

    •The SQL Server registry keys must be consistent.

    •The CPU architecture of the installation program must match the CPU architecture of features intended for upgrading.

    •If the computer is clustered, the cluster service must be online.

    •Windows PowerShell must be installed. (Setup will do this automatically when it installs prerequisites.)

    •SQL Server Setup must be supported on this operating system platform.

    •SCC checks whether a pending computer restart is required.

    •The existing performance counter registry hive must be consistent.

    •SCC checks that neither SQL Server 7.0 nor SQL Server 7.0 OLAP Services is installed on the server. SQL Server 2008 is not supported on the same server that has SQL Server 7.0.

    In above points, how to make sure the below:

    The existing SQL Server registry keys must be consistent?

    The existing performance counter registry hive must be consistent?

    Thanks
