Upgrading Servers from Windows 2008 32-bit to Windows
2008 R2 64-bit
ShoreTel supports a particular 64-bit version of the Windows Server 2008 operating system.
Specifically, support for Windows Server 2008 R2 64-bit only (no non-R2 versions) began with the first
release of ShoreTel Release 11 (Build Number 16.5.8506.0) and continues in subsequent builds.
Be aware that after the ShoreTel software is installed on the server, the server is considered a
Telephony Appliance. As a Telephony Appliance, it does not adhere to the same policies, procedures,
or security as a data server.
Release 11 Build 16.5.8506.0 and higher supports heterogeneous environments. For example,
ShoreTel Release 11 software or higher supports a mix of the Headquarters Server and DVSs running
either the 32-bit OS or the R2 64-bit OS until you get to version 13. In ShoreTel 13, Windows 2003 is
no longer supported.
Verify that the version of the Uboot code on all switches is 1.1.3.27 or later prior to the installation of
Windows Server 2008 R2 on the headquarters system. Use Quick Look to confirm the version of boot
ROM on each switch. Only ShoreTel 12.3 and above has this new Uboot code.
If you are not on ShoreTel 12.3 or above and you are upgrading to Windows 2008 R2 (64-bit), follow
the procedure in Upgrading Servers from Windows 2003 32-bit to Windows 2008 R2 32-bit or 64-bit on
page 225.
