IBM Tivoli Storage Manager, Version 7.1

Planning the upgrade of the server

Planning the upgrade to Tivoli® Storage Manager V7.1 is important because, in addition to installing the new software, you must move the contents of the V5 server database into the V7.1 database.

About this task

Tivoli Storage Manager V5 servers can be upgraded directly to V7.1. However, Tivoli Storage Manager V7.1 servers cannot be used with V5 clients or with other servers in the system that are at V5. Unless all V5 clients and V5 servers can be upgraded at the same time, consider upgrading the server to a level that can be used with V5 clients and V5 servers. Then, upgrade all servers and clients to V7.1 when possible. For information about the levels of the Tivoli Storage Manager server that can be used with V5 clients and V5 servers, see the following technotes:

When you move data from a V5 server database to a V7.1 database, a large amount of system processing capacity is used. The move also requires a large amount of I/O activity.

Procedure

As you start to plan the upgrade process, consider the following options:

You can test the upgrade on nonproduction systems. Testing gives you information about how long the upgrade of the server database takes, which will help you to plan for the time that the server will be unavailable. Some databases might take much longer than others to upgrade. Testing also gives you more information about the size of the new database compared to the original, giving you more precise information about database storage requirements.
If you have multiple servers, you can upgrade one server first, to determine how the upgrade process will work for your data. Use the results of the first upgrade to plan for upgrading the remaining servers.
