My account rep put this together for us from some new briefs; I think
you may find it informative. It has one surprise for me and that was
that Windows 2003 CALs can be recycled for use with Windows Server R2.
Please see below.

Many of you have been asking about licensing for Windows Server 2003 R2.
Given this, I have put together this email which should assist you with
your questions regarding this new product.
Windows Server 2003 R2 Now Available
Doing more with less just got better! Windows Server 2003 R2 simplifies
branch server management, improves identity and access management,
reduces storage management costs, provides a rich Web platform, and
offers cost-effective server virtualization.
Licensing for Windows 2003 R2:
* Microsoft Windows Server 2003 R2 is an update release of
the Windows Server 2003 operating system and contains new functionality
that is not available anywhere else. If you want to upgrade to Windows
Server 2003 R2, you will need to purchase a Windows Server 2003 R2
license for each server that you will be upgrading. Unlike service packs
and feature packs, Windows Server 2003 R2 is the full operating system
and requires a new server license. Customers that have their Windows
Servers covered under Software Assurance will receive R2 at no charge.
* Windows Server 2003 R2 is priced and licensed the same
way as Windows Server 2003. No pricing changes have been made. Windows
Server 2003 R2 will be available through all the regular sales and
* New CALs are not required for Windows Server 2003 R2.
Existing Windows Server 2003 CALs will work with Windows Server 2003 and
Windows Server 2003 R2.
* Volume license customers who have servers under Software
Assurance or as part of their Enterprise Agreement will automatically
receive Windows Server 2003 R2 as part of their Select CD disk
* What are the differences between Windows 2003 Service
Pack 1 and Windows Server 2003 R2?
Windows Server 2003 Service Pack 1 (SP1) provides product updates to the
Windows Server 2003 operating system. Windows Server 2003 SP1 contains
additional features to increase security and improve functionality.
Windows Server 2003 SP1 is a free product update and can be easily
downloaded or ordered on CD.

Windows Server 2003 R2 is an update release of the Windows Server 2003
operating system that is built on top of Windows Server 2003 SP1 and
includes new product features, including improvements to branch office
management, identity and access management, and storage management.
Windows Server 2003 R2 requires a new server license and is available
for purchase through the same channels as Windows Server 2003.
Licensing in Virtualized Environments
* Through the Dynamic Systems Initiative (DSI), a
cross-company effort to address customers' desire to be more cost
efficient, proactive, and responsive to business requirements, Microsoft
is making it easier to take advantage of the benefits of server
virtualization technology. Organizations that virtualize computing
environments can increase operational efficiency through server
consolidation, application re-hosting, disaster recovery, and software
test and development.
With the help of customers, partners, and industry analysts, Microsoft
has developed new licensing and use rights to better enable customers to
reap the benefits of virtualization and to accommodate advances in
technology. These use rights take effect with Windows Server 2003 R2
Changes in Use Rights for Windows Server 2003 R2 Editions
* Running the software versus installing and using the
Previous server license requirements for Windows Server 2003 products
were based on the number of installations of the product on a server.
License requirements for the software are now based on the number of
instances of server software that you "run" on a server. Each software
license now specifies the number of instances of software that you may
run on a particular server at a time, rather than the number of copies
of the software that you may install and use on that server.
* Creating and storing instances
Previous use rights for Window Server 2003 products allowed only one
installed copy per license. You were required to license each additional
copy separately. Now, use rights for Windows Server 2003 R2 allow you to
create and store any number of instances of the software on any of your
servers or storage media. This right to store many instances provides
additional flexibility and makes it easier for you to run those
instances on any of your licensed servers. This is a benefit for
virtualization scenarios in particular where you might want to create
and store instances of the software in virtual machines but run only a
subset of them on a server at any time. Please note that you must
properly license each server on which you run these stored instances.
* Using software designed for other platforms
Previous retail software license terms for Windows Server 2003 products
did not allow for migration from a 64-bit platform to a 32-bit platform
or vice versa. Use rights were specific to the platform type that was
licensed. Now, a license for a platform-specific version of Windows
Server 2003 R2 permits you to use (in place of what you have licensed)
the software for the other platform. The software must be the same
version and edition. For example, under a license for Windows Server
2003 R2 Standard x64 Edition, you may run Windows Server 2003 R2
Standard Edition in place of Windows Server 2003 R2 Standard x64
Edition. In some virtualization scenarios, customers may need to run a
32-bit version of the software in the virtual machines to support legacy
* Expanded Use Rights for Specific Editions to Support
Microsoft is also expanding use rights for Windows Server 2003 R2
Enterprise Edition and Windows Server 2003 R2 Datacenter Edition. These
expanded use rights are summarized below. They apply only to the
specific editions described. They do not apply to previous versions of
these products. Note that Windows Server 2003 R2 Datacenter Edition is
available via original equipment manufacturers (OEMs) only.
* Windows Server 2003 R2 Enterprise Edition Use Rights
Microsoft has added two important licensing benefits to Windows Server
2003 R2 Enterprise Edition. First, under a single license on a server,
you may run up to four instances of the server software in virtual
operating system environments on that server (only one instance per
virtual operating system environment). Second, if you are licensed for
Windows Server 2003 R2 Standard Edition, you may run an instance of
Standard Edition in place of Enterprise Edition in any of those virtual
operating system environments. Customers will find key benefits in
licensing Windows Server 2003 R2 Enterprise Edition as their
virtualization platform but may still need to run Windows Server 2003 R2
Standard Edition within the virtual machines. Microsoft has enabled this
scenario as a significant benefit to licensing Windows Server 2003 R2
* Windows Server 2003 R2 Datacenter Edition Use Rights
Microsoft has also added two important licensing benefits to Windows
Server 2003 R2 Datacenter Edition. First, under the Datacenter Edition
license, in addition to running one instance of the software in a
physical operating system environment per hardware partition on a
licensed server, you may run one instance of the software in a virtual
operating system environment per licensed processor on that server.
Second, if you are licensed for Windows Server 2003 R2 Standard Edition
or Enterprise Edition, you may run an instance of Standard Edition or
Enterprise Edition, respectively, in place of Datacenter Edition in any
of those virtual operating system environments. For more information on
use rights for Windows Server 2003 R2 Datacenter Edition, contact your
OEM. Windows Server 2003 R2 Datacenter Edition is available via OEMs
only. For more information about Datacenter Edition visit the Windows
Server 2003 Datacenter Edition home page
* Client Access Licenses and External Connectors for
Windows Server 2003 R2 Editions
With the launch of Windows Server 2003 R2, we have made an exception to
requiring that your Client Access Licenses (CALs) and External
Connectors for Windows Server 2003, Windows Server 2003 Terminal
Services, and Windows Server 2003 Rights Management Services be upgraded
to access Windows Server 2003 R2 Editions. We have not created new CALs
specific to Windows Server 2003 R2 Editions. In other words, Windows
Server 2003 CALs and External Connectors may access Windows Server 2003
R2 Editions. We recommend that you purchase Software Assurance for your
servers and CALs in order to use the latest Windows Server release and
to take advantage of the many benefits of the Microsoft Software
