Apple System 7 Pro - Manual (Page 15)

Apple recommends upgrading all AppleTalk networks to Phase 2.
AppleTalk Phase 2 software is installed on your Macintosh or PowerBook when
you install System 7 Pro. This does not affect communication on LocalTalk or
TokenTalk connections. However, any EtherTalk user upgrading to System 7 Pro
(and thereby installing the Phase 2 EtherTalk driver) can communicate only
with other AppleTalk Phase 2 users.
A Macintosh running router software does not need to be upgraded to system
software version 7.1.1 when you upgrade other computers on the network.
However, the router must support AppleTalk Phase 2.
The AppleTalk Internet Router from Apple works with both System 7 and System
6.
What kind of support will users need most?
The most important tasks for users installing System 7 Pro are checking
Macintosh and PowerBook disks for software compatibility, installing the
software, and getting acquainted with the new features.
To help users in these tasks, make sure they rely on the tools provided with
the software: the Compatibility Checker program, the PowerTalk User's Guide,
the booklet What's New in System 7 Pro, and Balloon Help for on-screen
assistance.

Upgrading all at once or in stages
Whether you perform the group upgrade all at once or break the process into
stages depends on the size of your network or internet and the availability
of personnel to help users with the upgrade.
Users may need help installing the new software, upgrading their application
programs and drivers for their peripheral equipment, and learning to use the
new features of the software.
On a large internet with many users, it's preferable to select one group or
department to upgrade first and install an upgrade server on that group's
local network. You can use this first group upgrade to become familiar with
users' support needs.
The number of users per server
The number of users who can share an upgrade server is subject to the limits
of your software license agreement.
The number of upgrade servers you should set up also depends on several
