Installation Prerequisites
The installation script works in the following environments:
Note: CentOS Stream 9 is supported for new instances of Composer 24.3 and higher. Contact Support for upgrade assistance from earlier versions.
Upgrade and Migration Considerations
Windows Server 2012R2 is not compatible with both Java17 binaries and the latest releases of Composer (23.2 and later). We recommend you use Windows 2016 or later to run Composer 23.2 and later.
In general, you can upgrade directly to the latest version of Composer from a prior version.
If you are upgrading to a newer version of Composer and you also want to change your encryption mode, perform the upgrade first and then complete the steps described in Change the Encryption Mode.
Note: New installations of Composer (v24.3 and later) use PostgreSQL 16. If you are upgrading your environment to v24.3 or later, you can retain your existing PostgreSQL version.
Important: If you are upgrading to a newer version of Composer and have created an attribute named User.timeZone
, this may be overwritten on upgrade. See Upgrade Workflow for more information about preparing your environment for the upgrade process.
Upgrading with Kubernetes
Java Considerations
Java 11.0.5 is required to run Composer 23.1 and Java 17 is required to run Composer 23.2.
An option to install OpenJDK is included in the installation and upgrade scripts provided by Composer. If you skip this option or if you install or upgrade the product manually, make sure that Java 11.0.5 is installed for Composer 23.1 and Java 17 for Composer 23.2. If you do not, Composer will not start after the installation.
Target Server Prerequisites
The target server for the Composer software should meet the following prerequisites:
The server must be connected to the Internet.
If this is a new (fresh) installation, the server must not have PostgreSQL already installed. (Not required for upgrades.)
If this is a new (fresh) installation, the server must not contain any
zoomdata
folders or property files from previous versions. If a previous version of Zoomdata or Composer was installed on this server, ensure that all property files have been deleted before running the installer script.(Not required for upgrades.)The user installing Composer must be able to use the
sudo
command on the server on Linux platforms orAdministrator
privileges for the server on Windows platforms.
If you do not have an internet connection on the server on which Composer is being installed, download the Composer installation package and load it onto the target server. After this is done, you can manually install Composer. See Install Composer Manually.
If the server on which Composer is to be installed does not meet all the prerequisites, see Alternative Installation Options.
In addition, Composer benefits from having time synchronization in your network. Specifically, Composer leverages the Network Time Protocol daemon (NTPD), which performs time synchronization of networked servers to Coordinated Universal Time (UTC). If needed, read Use the Network Time Protocol to Synchronize Time for instructions to set this up.
After you have made any needed adjustments to your network configurations, you can continue the installation process.
