"Under Microsoft's planned enterprise licensing rules, businesses that
buy PCs before April 23, 2010, with Windows 7 preinstalled can
downgrade them to Windows XP, then later upgrade them to Windows 7 when
they're ready to migrate their users. But PCs bought on or after April
23 can only be downgraded to Vista -- which is of no help for XP-based
organizations, Silver notes -- and could cause major headaches and add
more costs to the Windows 7 migration effort."http://www.infoworld.com/d/windows/microsofts-looming-windows-7-licensing-disaster-xp-users-639
"Both Forrester Research and Gartner advise clients to wait 12 to 18
months after Windows 7 ships before adopting the new OS, so they can
test compatibility of their hardware and software, as well as ensure
their vendors' Windows 7 support meets their needs. But Microsoft's
six-month downgrade restriction for XP means that the businesses that
chose not to install Vista have to rush the migration process. Or they
can spend extra money and enroll in Microsoft's Software Assurance
program, which then lets them install any OS version at the price of
the extra yearly fee (about $90) per PC."
IT needs to work through several other issues when figuring out its Windows 7 migration strategy, Silver points out.
- Microsoft has yet to make public the details of its
Technology Guarantee program or even say if there will be one that
covers business purchases. The Technology Guarantee program gives free
upgrades to Windows 7 on PCs purchased after a certain date. That's
crucial for businesses that plan to adopt Windows 7 soon, so they can
time their hardware purchases to avoid paying for a Windows 7 upgrade
shortly after buying a PC shipping with Vista.
- Even if
applications designed for XP or Vista run on Windows 7, that's no
guarantee that the software vendor will support them on Windows 7.
