It is highly recommended to prepare for migration of your applications to the next SharePoint version 2010, if any one of the following is applicable.

  • performance of the server farm is not meeting customers’ expectations,
  • the user base is growing rapidly,
  • the application pools are recycling more and more often
  • a scheduled equipment upgrade is approaching.

The basic requirement for 2010 is listed below..

  • SharePoint Server 2010 will be 64-bit only.
  • SharePoint Server 2010 will require 64-bit Windows Server 2008
  • SharePoint Server 2010 will require 64-bit SQL Server 2008 / 2005.
  • SharePoint 2010 will support only Internet Explorer 7, Internet Explorer 8 and FireFox 3.x IE6 is not supported.

Things to know/remember about 64 bit environment.

  • Not all 64-bit processors are supported. For example, Intel’s Itanium series of 64-bit processors uses a proprietary design that is not compatible with Microsoft SharePoint Products and Technologies. So research before ordering new hardware.
  • A 64-bit system architecture that is running a 64-bit edition of Windows Server can support up to 1,024 GB of both physical and addressable memory.
  • 64-bit environment does not require worker processes to cycle as often, so it can support more user base/server. So basically you can reduce number of servers in the farm to support more users compared to 32 bit environment.
  • In 64 bit environment(hardware/server/DB all 64 bit), it is possible for SQL Server to get very large working data sets entirely into RAM, thereby improving performance and scalability.
