Hardware Minimum requirements

Hard disk 80 GB for system drive.
Provide sufficient disk space for content databases
and projected growth and peak period usage.
Maintain sufficient free space for memory swapping,
which is normally twice the amount of memory in a
production environment.

Database Servers
The following table describes the minimum hardware requirements for database
servers.
Hardware Minimum requirements
Processor 64 bit, four cores for small deployments.
64 bit, eight cores for medium deployments.
RAM 8 GB for small deployments.
16 GB for medium deployments.
Use SQL Server capacity recommendations for large
deployments.
Hard disk 80 GB for system drive.
Provide sufficient disk for content databases and
projected growth for peaks and growth.
Maintain sufficient free space for memory
swapping, which is normally twice the amount of
memory in a production environment.

Minimizing Downtime

Key Points
All upgrades take time and resources, but you must minimize your farm downtime
so that your organization can remain productive.
Read-Only Content Databases
For many databases, and particularly Web publishing environments, most
transactions are reads rather than writes. You can maintain content availability by
providing a read-only version of the data that users can access while you update
the original database. You can deliver this productivity by locking the copy version
through SQL Server. SharePoint 2010 is coded to automatically trim all update
functionality from the UI when it presents information from a read-only database.

Note: The use of read-only databases requires different server machines, because you
cannot install both Office SharePoint Server 2007 and SharePoint 2010 server code on
the same system. You may also consider different systems for databases, because the
production processes and the upgrade process may cause performance issues. You can

test to see whether this may be a problem; however, it is difficult to develop a test

scenario that behaves exactly like a production environment.

Note: This solution is available for content databases only; service databases will not
work as expected if set to read-only.
Parallel Database Upgrades
You can plan to perform parallel database attach upgrades through a manual
process. SharePoint 2010 supports multiple sessions, which means that you can
upgrade more than one database at a time. You must test your hardware to
establish how many upgrade sessions you can run concurrently.
Content Database Attach with Alternate Access Mapping Redirection
If your organization must upgrade in phases, you can plan to use the redirect
functionality that is now available to alternate access mapping in SharePoint 2010.
This is a complex option and has a large number of manual steps to achieve a
working solution. You may also need to use additional tools to complete the
process, such as URL fix-up tools for InfoPath forms and form templates. This
process does not replace an automated gradual upgrade system with a manual one.

Using Visual Upgrade

Key Points
If business users have a reason for maintaining the look and feel of their
SharePoint environment, such as the need for additional training, you can choose
to maintain the appearance of Office SharePoint Server 2007 in an upgraded
SharePoint 2010 site. SharePoint 2010 ships with Office SharePoint Server 2007
master pages and cascading style sheets (CSS) so that you can preserve application

appearance. This is the default when you upgrade.
There are properties on each site collection and site that you can use to specify a UI
version for the site. Setting 3 specifies the Office SharePoint Server 2007 UI, and
setting 4 indicates the SharePoint 2010 UI.
As part of your test plan, and later for education, you can preview the new UI at a
site collection or site level. You can delegate the UI migration to site collection
administrators.

Note: If you make changes to pages or add new pages while in preview mode, these
pages may not work as expected if you revert to Office SharePoint Server 2007.

You should note in your plan that some pages only work in the new UI version:
• The My Site host page, although individual site page do revert.
• A Project Web Access site collection.
• Report Server Web Parts.

The new UI uses strict mode XHTML. This may cause issues in rendering, so you
should test all screens and Web Parts as part of your visual check of upgraded
pages in the SharePoint 2010 UI mode.
