Single server and single farm.
It has SP foundation 2010. I then upgraded it to SP 2010 server SP1 (by first installing SP 2010 server followed by SP 2010 foundation SP1 and then server 2010 SP1 and finally Aug 2012 CU. At the end I rebooted machine and then ran CONFIG utility and then rebooted again).
I see that central admin opens and I am able to create sites etc.
Whats happening is the old site that was there with SP foundation 2010 is not accessible. When I click on it, I get below error,
An unexpected error has occurred.

I tried to look in the 14 hive logs but I see only "usage" files and log files are zero bytes. The application event log has few errors as listed below.
Event IDs are below
7043 - Load control template file /_controltemplates/TaxonomyPicker.ascx failed: Could not load type 'Microsoft.SharePoint.Portal.WebControls.TaxonomyPicker' from assembly 'Microsoft.SharePoint.Portal, Version=188.8.131.52, Culture=neutral, PublicKeyToken=71e9bce111e9429c'.
2137 - The SharePoint Health Analyzer detected an error. Drives are running out of free space. Available drive space is less than twice the value of physical memory. This is dangerous because it does not provide enough room for a full memory dump with continued operation. It also could cause problems with the Virtual Memory swap file: (CRMLAB01 - C:).
Examine the failing servers and delete old logs or free space on the drives. For more information about this rule, see "http://go.microsoft.com/fwlink/?LinkID=142688".

7362 -Object Cache: The super user account utilized by the cache is not configured. This can increase the number of cache misses, which causes the page requests to consume unneccesary system resources. To configure the account use the following command 'stsadm -o setproperty -propertyname portalsuperuseraccount -propertyvalue account -url webappurl'. The account should be any account that has Full Control access to the SharePoint databases but is not an application pool account. Additional Data:
Current default super user account: SHAREPOINT\system
As of now, the newly created web application and it's site atleast renders. I am still testing the old site (that got upgraded from SP foundation to SP server 2010).
