Performing the upgrade

Review the descriptions of each upgrade procedure to determine how to perform your upgrade.

You can have more than one installation, with the same or different versions, of Rational® Synergy on a given computer, for client and engine software. Your existing Rational Synergy databases can run on one or more servers.

On Windows, you cannot have more than one Rational Synergy Informix® server per computer, even for different releases of Rational Synergy. Installing a Rational Synergy 7.2 server on a Windows computer upgrades any previously existing Rational Synergy servers. It also disables the use of those servers under the earlier releases.

As a result, there are two ways to upgrade your databases from earlier releases.

Methods for performing upgrades

Choose from one of the following upgrade procedures for each server:
  • Upgrading a new server
    • Create a 7.2 server on a different computer, and then, copy your databases to this new server, and upgrade them. Databases can be copied to the new server by using ccmdb pack. Then, use ccmdb unpack. Perform this procedure when you test Rational Synergy 7.2. After you have completed testing, use it again when you upgrade production databases for live use.
  • Upgrading an existing server
    • Upgrade an existing server to 7.2, and upgrade all the databases in that server. Installing 7.2 using this procedure immediately performs the server upgrade, and renders the databases unusable under previous releases. Each database on the server must be upgraded to 7.2 before it can be used. It is not required to move or copy the databases because they are already in an upgraded server. Do not use this procedure while testing Rational Synergy 7.2. However, you can use it after you have completed testing on a separate server.
Note: You can use different procedures for different servers.

To determine which method to use, review the following checklists.

Upgrading an existing server checklist

Use the procedures in the Upgrading an existing server if all of the following items pertain to you:

Note: You receive some performance benefits if you choose to create an Informix database server. Your databases are unpacked, which causes the database indexes to be rebuilt and the data to be defragmented, This process improves performance.

Upgrading a new server checklist

Use the procedures in the Upgrading a new server if any one of the following items pertain to you:
