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.

Hi,
You can follow the guide below to do the in-place upgrade:

If you believe your server is still a good candidate for an in-place upgrade, here are some important things you should know about before doing an in-place upgrade:

thanks for the information ..


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

https://docs.microsoft.com/en-US/troubleshoot/windows-server/deployment/fix-windows-update-errors#resolution-for-windows-7-service-pack-1-sp1-and-windows-server-2008-r2-sp1

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