Phased Upgrade of a Running Client/Server System

Chapter 230

Step 4. Restart the SNAplus2 software.

For each Windows client in turn, use the procedure in “Upgrading a

Windows Client”.

Changing the Conﬁguration during the Upgrade

Process

While the network contains both Release 5 and Release 6.0 or 6.1

computers,you can manage both usingRelease 5 administration tools, as

long as you are not using any new Release 6.0 or 6.1 features.

CAUTION If you use the Release 6.0 or 6.1 administration tools to conﬁgure new

features on Release 6.0 or 6.1 servers, and then subsequently use

Release 5 tools, the conﬁguration information for the new features will

be lost.

Adding New Servers or Clients During the Upgrade

Process

If you need to add a new computer, either a server or a client, to the

SNAplus2 system while you are in the process of upgrading it,you can do

either of the following:

• Install the R5 software on this computer. This procedure ensures

that the new computer can access the resources of all servers, both

Release 5 and Release 6.0 or 6.1, as soon as it is installed. You then

need to upgrade it later to the new release. Add the machine in the

same way you added the existing servers and clients, following the

same order as described earlier in this section (servers in order of

precedence, and then clients). If you are adding a server, this server

cannot become a master or backup server until it is upgraded

(because you cannot change the sna.net ﬁle on back-level servers

during the upgrade process).

• Alternatively, you can install the Release 6.0 or 6.1 software on this

computer. Installing this software will avoid having to upgrade later,

but it means that the new computer can access only resources on

Release 6.0 or 6.1 servers (either new or upgraded).
