Upgrade Semarchy xDM

This page provides a summary of the process for upgrading the Semarchy xDM platform from earlier versions.

Before the upgrade

Review the documentation

Before starting the upgrade, consider the following:

  • Refer to the latest release notes to stay informed about new features, bug fixes, and more.

  • Familiarize yourself with the installation instructions and system requirements for Semarchy xDM.

  • Understand any major changes that could affect your upgrade, and make sure to review the pre-upgrade actions before starting the upgrade process.

  • Depending on your current version, certain actions may be required after the upgrade. Make sure to review the post-upgrade actions before starting the upgrade process.

Understand release versions and types

Semarchy xDM releases are identified by a version number and a release type (e.g., 2023.1.0 LTS).

Version number

Version numbers in Semarchy xDM are expressed in the following format: <major_version>.<minor_version>.<patch_version> (e.g., 2023.1.0).

The first two numbers reflect the year and quarter of the first GA release for a given minor version. For example, xDM 2023.2 was released in the second quarter of 2023.

Patches increment the <patch_version> number. For example, patches for the initial 2023.2.0 release are numbered 2023.2.1, 2023.2.2, etc.
Although these patches occur later in time, the first GA release date for 2023.2 remains unchanged.

Release type

Releases also have a release type:

  • Mainstream support (MS) releases occur quarterly and introduce new features. MS releases accelerate the availability of new features for customers who want access to the latest improvements and enhancements as soon as possible.

  • Long-term support (LTS) releases typically occur every year and consolidate features introduced by the previous MS releases. They are maintained and supported for a longer time. LTS releases provide an option more suited for slowly changing environments, or for customers who prefer a fully supported environment for an extended time without having to apply upgrades other than patches.

The first release date and the release type define the end-of-maintenance and end-of-support for a given release.

For additional information regarding LTS and MS release types, see our Global support policy on the Semarchy website. This page also lists release dates and support timelines for each release.

Major, minor, and patch upgrades

An upgrade may be a major upgrade, a minor upgrade, or a patch. The differences between the old version number and the new version number define the type of upgrade.

  • A major upgrade takes place as soon as the major version number differs. Major versions include major feature changes and typically require repository and data location upgrades. For example, upgrading from 5.3.0 to 2023.1.0 is a major version upgrade.

  • A minor upgrade takes place when the major version remains the same but the minor version differs. Minor versions include minor feature changes and typically require repository and data location upgrades. For example, upgrading from 2023.1.0 to 2023.2.0 is a minor version upgrade.

  • A patch is only applied when the patch version differs. Patches do not require repository and data location upgrades and are easily reversible. For example, upgrading from 2023.1.0 to 2023.1.3 is patching.

Although the process is the same for all types of upgrade, be aware that the repository and data location upgrade steps may be skipped for patches.

Unless otherwise specified, the upgrade path between two versions of Semarchy xDM is direct. You do not need to install intermediate versions.

Select the upgrade path

The upgrade supports two paths:

  • An in-place upgrade consists in installing the new version of Semarchy xDM in place of the previous version and upgrading the existing repositories. With this method, you can revert the environment to its original state by restoring the backup of the server folders and database schemas.

  • An out-of-place upgrade consists in replicating the existing Semarchy xDM environment and upgrading the copy. The original environment remains unchanged.

You may choose one of the two paths depending on your IT infrastructure policies for upgrading.
