3.Click Convert to Cluster. After the ClusterIT utility completes, IDS starts on the secondary node.
| After implementing a cluster environment on multiple nodes, you can find a |
| record of the ClusterIT utility activities in the clusterIT.log files, one for |
| clusterIT_a in the primary node directory, and one for clusterIT_b in the |
| secondary node directory where the ClusterIT executables were installed. |

Upgrade of IDS by Overwriting an Existing Installation | |
Use the installation application to overwrite an existing IBM Informix Dynamic | |
Server installation only when you are upgrading from a previous fix pack of the | |
same version number or for specialized technical environments. | |
When you place the IBM Informix Dynamic Server installation media on a | |
Windows computer that hosts an earlier version of the server, you will be | |
prompted as to whether you want to install in a different directory or upgrade by | |
installing in the same directory where the older version of the product already | |
exists. | |
For upgrading or migrating a production database server, choose to install in a | |
different directory as documented in the IBM Informix Migration Guide unless you | |
have specific goals or system constraints that require you to overwrite the older | |
installation completely. The following are some examples of when you might | |
upgrade by installing directly to the directory where an earlier version or fix pack | |
level are located: | |
v Upgrade an existing IDS installation that has the same version number as the | |
new product, but is an earlier fix pack. For example, if the host computer has | |
IDS 11.50.xC1 and you want to install IDS 11.50.xC4, then complete the upgrade | |
by installing in the same location. | |
v Capture the installation settings in a response file so that you can upgrade other | |
older IDS instances with silent installation. | |
v You have a computer hosting an older version of IDS that does not have | |
sufficient free space to hold two installations of the product. | |
v You plan to use a symbolic link to migrate the data to the new version. | |
Overwriting an Existing IDS Installation | |
Ensure that you complete the prerequisites before you do an upgrade that installs | |
the product in a directory that already has an earlier version. | |
Important: Ensure that you have the installation media for the IBM Informix | |
Dynamic Server version that you are replacing, back up your databases, and | |
complete other preparation steps before you upgrade using the following method. | |
See the IBM Informix Migration Guide for details about supported upgrade paths | |
and data migration. | |
When you install using the procedure below, the old version or fix pack of the | |
product is uninstalled. | |
1. Open the IBM Informix Dynamic Server installation application of the version | |
or fix pack level that you want to install. | |
2. Select the option to install a new instance when the installation application lists | |
existing IDS instances and click Next. | |
3. Select the option to upgrade by replacing the product and click Next. Complete | |
the prompts in the server installation application for a typical or custom setup. |
