I am interested in upgrading my exisiting windows server 2003 R2standard edition with Service Pack 2 to a 2008 R2 server. This is my one and only Domain controller. It also provides file sharing, print server. Would it be feasible and okay to do an inplace upgrade? I realize that I need to makea very good backup of AD and files to ensure things go smoothly. I also realize that while in the process of upgrading the domain would be unavailable. I have a seperate exchange 2007 server and several other member application servers. Any advice is greatly appreciated and if you have any instructions or guides that I could follow to ensure a smooth upgrade I would appreciate it.Thanks,ZachZach

Windows 2008 R2 is a complete 64bit operating system make sure that your existing windows 2003 R2 is on the 64Bit platform to be upgraded.see thesupported upgrade paths herehttp://technet.microsoft.com/en-us/library/dd979563(WS.10).aspxNote: Before Doing and Inplace upgrade make sure that you have your system state backedup.Also see the how to upgradehttp://blogs.dirteam.com/blogs/sanderberkouwer/archive/2008/04/08/upgrading-your-active-directory-to-windows-server-2008.aspxhttp://technet.microsoft.com/en-us/library/ee522994(WS.10).aspx http://technetfaqs.wordpress.com

Hi ,Did syed's suggestion helped you answer your questions ?

Syed's suggestion was very helpful. I have been doing a considerable amount of reading and will probably plan on doing an in place upgrade. Prior to doing this I am going to make an image of my existing 2003 server in case things don't properly I can just reimage and be back in business.Zach
