I am planning to move SharePoint 2007 from a Windows 2003 32-bit system to a new Windows 2008 R2 64-bit server tomorrow afternoon. I have done much research and found only one article that gives me enough information to go on for the migration. Others in technet have cited this article; so, I expect it is the one go use. However, before I begin, I wanted to see if anyone has anything else to add. Here's the article I'm planning to use: http://www.combined-knowledge.com/Downloads/2007/How%20to%20move%20MOSS2007%20from%20W2003_32bit%20to%20W2008_64bit.pdf Our current environment consist of one front end server (Windows 2003 32-bit running MOSS 2007) and one SQL server (Windows 2008 Standard 64-bit with SQL 2008 640bit). So, we don't need to move the SQL databases - just the SharePoint front end. We are moving to Windows 2008 R2 with MOSS 2007 (same SP and patch levels are planned). Our final goal is to move to SharePoint 2010 in the next week or two, but this seems to be the required first step. Most of what I've read online contradicts other things. I've found no consistency between articles. Thank you in advance for your assistance.

did you check this technet article: http://technet.microsoft.com/en-us/library/dd622865(office.12).aspx I been went through this upgrade process, i did the follow steps. i took the full back of CA, 12hive and IIS. backup of all content dbs in SQL server then i blow up the farm and update the server with win2k8 standard edition then Install the MOSS 64bit version and after running the config wizard i restore the full back and here we go, everything went well. Note: just make sure your service account have the the right permision. thanks wsi am at SharePoint administrator

Hi waqas, When you mention you did a full backup of CA, 12 hive and IIS, do you mean just using "Full Backup" from Central Administratiom page? Is that enough? Ajohansen, I am going to the same process as you mentioned. SQL Server already in x64, WFE with x86. Have to update this WFE to MOSS 2007 x64 and afterward to SPS2010. Can you please, tell me, how did it go with you? Did you followthe article you mentioned? Any issue to mention? Many thanks in advance.
