Limitations
Before planning your upgrade, refer to the following rules and support limitations:
■ The utilities do not support Remote Boot and Configuration Services (RBCS) or
network booting.
■ Upgrades from NETBuilder bridge/routers running version 7.x, or earlier, are not
supported.
■ You cannot upgrade to a different platform. For example, you can only
upgrade an OfficeConnect
®
bridge/router to an OfficeConnect bridge/router.
You cannot upgrade a SuperStack
®
II NETBuilder bridge/router to a
SuperStack II NETBuilder SI bridge/router. The only exception is an upgrade
from a NETBuilder II
®
CEC module to a DPE module.
Take Time to Plan Because networks today have become increasingly complex, upgrading your
network requires a systematic approach. 3Com recommends that you plan your
upgrade carefully before implementing it. See Chapter 3 to plan your upgrade.
