Before starting the upgrade processes, OpenText recommends that you make sure you have the requirements for a Retain 23.4 system, as outlined in System Requirements
in OpenText Retain CE 23.4: Planning.
By default, the Retain installation program uses an Internet connection to download a specific version of Java for each version of Retain. If the Retain server is not connected to the Internet, you must prepare the server with a workaround beforehand. Otherwise, the installation fails.
The following sections outline the preparation steps for each Retain version in the supported upgrade path as well as for installing the current Retain release.
Prepare your Linux Retain server by using the information in the row that matches your target version.
On a workstation with an Internet connection, use the links in the following table to download the linked Java version that applies to your upgrade target. Then refer to the Action column for further instructions.
