I've been asked a few times to summarize the basic installation prerequisites for clients getting started with the SharePoint 2010 public beta.
As I've noted before, SharePoint 2010 will be a 64 bit only platform. There are no direct upgrades from 32 bit servers to 64 bit servers, so you will need to build a new 64 bit patform and migrate content to it. Minimum requirements for the server OS are Windows Server 2008 or Windows Server 2008 R2 X64.
On the database side, the minimum requirements are:
- SQL Server 2005 x64 SP3 with Cumulative Update 3
- Or
- SQL Server 2008 x64 SP1 with Cumulative Update 2
Those cumulative updates are not suggestions -- SharePoint 2010 will not install without them.
Finally, although the prerequisite checker is pretty thorough, I found another undocumented prerequisite. SharePoint uses token authentication without requiring transport security. The .NET Framework 3.5 SP1 made WCF transport security a requirement for token authentication, so this hotfix lifts the requirement for SharePoint (which isnt using transpiort security by defualt.) For more information, request the hot fix at http://code.msdn.microsoft.com/KB971831 .
Also, please remember - there is no go live license or upgrade path from the public beta to the release RTM version. Please DO NOT use the beta for production environments or any data that needs to be upgraded to SharePoint 2010's final release. Thanks.
