    An in-place upgrade is never recommended mainly because of corruption carry-forward. Better option is to clean install the operating system, patch fully, migrate roles over to new one.

    Suppose the current windows 2008 already have some windows update, how to check if any of these update will block the upgrade process ?

    Updates would not block upgrade.
    I'd verify system and servicing health by running;
    sfc /scannow

    also system update readiness tool

    Then check for errors in;
    %SYSTEMROOT%\Logs\CBS\CheckSUR.log
