Steps to Upgrade SharePoint 2007 to SharePoint 2010

Steps to Upgrade SharePoint 2007 to SharePoint 2010

Recently I have a requirement is to migrate a SharePoint website created in wss3.0 to wss4.0. For moving the website to SharePoint 2010, you have to upgrade the WSS 3.0 to WSS 4.0. Follow these steps

1. Take the backup of current live website (wss3.0) using stsadm utility. 
2. Create a new machine having Windows 2008 64-bit R2 and SQL Server 2008 R2 Express 64-bit.
3. Install WSS 3.0 64-Bit and created a Site Collection using the same URL of the original server. Then patched it until it matched the 32-bit WSS 3.0 exactly.
4. Restore backup (created in step 1) on to newly created machine.
5. Once we had a working site on newly machine then simply install SharePoint Foundation 2010 and it upgraded the server to WSS 3.0 to WSS 4.0.
6. Upgrade all SharePoint custom web parts (previously build in 32 bit with VS 2008) as per 64 bit configuration.
