Upgrading Revit Server 2011 to 2012

I wanted to include the recommended process for upgrading a Revit Server from 2011 to 2012:

1. Ensure all users close out of Revit and any local or central projects they have open on the client workstations.
2. Apply a server-level administrative lock on the Central Server you will be upgrading to Revit Server 2012.   Lock the server name at the top of the tree:
   
   
   
   Process is located here.
   
   
3. Uninstall Revit Server 2011 from the Windows Server Control Panel.
4. Determine the Project and Cache directories in use for Revit Server.
5. Install Revit Server 2012 on the Windows Server.  Process for Central Server is located here.  Process for Local Server is located here.
6. Specify the same Project and Cache folder locations used for Revit 2011.
7. When the installation is complete unlock the administrative lock.  Process is located here.
8. Once the Central and all Local Servers are updated to Revit Server 2012, users can launch Revit from the client workstations.

As an optional first step you can also backup all data on the Central Server prior to uninstall \ reinstall.

Thanks Ryan. This does not yet exist in WikiHelp.
Also, it would still be nice to have a lightweight installer to remove 2011 and install 2012 or even just to install Revit Server 2012. Running it from the Autodesk_Revit_Architecture_2012_English_Win_32-64​bit.exe (3GB) file is pretty time consuming. Can we crack the installer open and just get a dedicated installer for RS2012 like we had for 2011 in the SAP (531MB)?

This information should be added to WikiHelp soon as well. Unfortunately there is no separate installer with the transition to 2012; it would need to be run off the standard installer. While there is an x64\Tools\RevitServer\RevitServer.msi file; do not install from this MSI. That is the core component that is utilized by the main installer. You will have no customization ability, and some features will not be properly installed if run separately. Just thought I would put this out there in case the question comes up or if anyone attempts to install 2012 in this manner. Thanks again.
