10. Software Downgrade Procedure
Teledyne LeCroy Xena continuously enhances the software for its systems, aiming to improve system performance and introduce new features. Therefore, it’s strongly recommended to always use the latest software version to maximize the capabilities of your systems.
However, in certain exceptional circumstances, you may find the need to revert to an earlier version of the system software. It’s important to note that only software versions available on the Teledyne LeCroy Xena website are officially supported by Teledyne LeCroy Xena.
For users who wish to downgrade their system to a prior software version, please follow the following instructions.
10.1. Install Earlier Version
The installer is specifically designed to permit upgrades of the system software. If your system already has a more recent software version installed than the package you are attempting to install, you will encounter the following messages as shown in Fig. 10.1.
To install an earlier version of Xena software you first need to uninstall the newer version. Use your standard software uninstall tools of your operating system to uninstall the newer Xena software package, before installing the earlier version.
You will find the guide to installing Xena software here: Installation - XenaManager User Manual.
