Upgrade from an earlier release of LiveCompare
If you are upgrading your server machine from an earlier release of LiveCompare, you will need to uninstall the earlier release before installing LiveCompare 2025.2 patch 1. All user data will be preserved if the same ‘User Data’ directory is chosen when installing the new version.
To uninstall LiveCompare, follow the instructions in the Installation and Configuration Guide for the earlier release. It is not necessary to uninstall the LiveCompare transports from SAP systems. Simply import the new transports to overwrite the existing objects.
Please note the following when upgrading from an earlier release of LiveCompare.
Back up the user data directory
Before upgrading to LiveCompare 2025.2 patch 1 or switching to a new database encryption configuration, back up the user data directory on your LiveCompare server by carrying out the following steps.
-
Make sure no users are signed in to LiveCompare, and that no workflows are currently running.
-
Stop the Tricentis LiveCompare Application Server service. This can be done by opening a command prompt with Administrator permissions on the LiveCompare server and running net stop rnserver.
-
Run regedit on the LiveCompare server and navigate to the HKEY_LOCAL_MACHINE\SOFTWARE\Tricentis\LiveCompare\2025.2\Settings folder.
-
Take a note of the UserDataDir value. This is the location of the LiveCompare user data directory.
-
Back up the directory referred to by the UserDataDir value.
-
Restart the Tricentis LiveCompare Application Server service by running net start rnserver from the command prompt.
Update custom apps and workflows that use Release Streams
Release Streams from LiveCompare 4.8 and 4.6 have been renamed as Pipelines. When upgrading to LiveCompare 2025.2 patch 1 from these earlier releases, any existing Release Streams are automatically converted to Pipelines. However, if you have any custom apps or workflows that use Release Stream parameters, these will need to be reworked to use Pipeline parameters.
Create new Smart Impact app variants
In releases of LiveCompare earlier than 4.8.0, the RFC Destinations and Test Repository used by the Smart Impact app were each provided as a separate parameter. However, in LiveCompare 2025.2 patch 1, RFC Destinations and Test Repositories used by the app (as well as Test Repository search, requirements and execution paths) are provided in a Pipeline. If you have upgraded to LiveCompare 2025.2 patch 1 from an earlier release and you have existing variants of the Smart Impact app, these variants won't work with the new app because they don't include Pipelines.
The Smart Impact App Variants Report workflow in the Tools templates folder generates an Excel report which includes the details for each of your earlier Smart Impact app variants. This report should be reviewed and used to create one or more Pipelines to cover each of the RFC Destination and Test Repository configurations required to perform each of your earlier analyses. These Pipelines should be used to create and run new variants of the Smart Impact app.
Update external data files
When an existing user data directory is specified during an installation, the <LiveCompare user data dir>\public\ExternalDataFiles folder is backed up to a folder named externaldatafiles_Backup_N, where N is one less than the number of backups that have been made. These files are used by the External Data Sources in the apps package. When an apps package is installed, any files from the package that already exist in the <LiveCompare user data dir>\public\ExternalDataFiles folder are overwritten by files from the apps package.
If you have modified any of the apps package’s external data files, you will need to copy the modified files from the latest <LiveCompare user data dir>\public\externaldatafiles_Backup directory to the <LiveCompare user data dir>\public\ExternalDataFiles folder. This will make the modified external data files available to LiveCompare’s External Data Sources following an upgrade.
Continuous impact analysis
If you have upgraded from LiveCompare 4.8 or earlier and have scheduled runs of the Configurator Impact Analysis or Security Impact Analysis workflows from your earlier release, note that the reports generated by these earlier workflows won't be listed in the Reports utility. You should run the Guided Configuration Migration Assistant workflow from the Tools templates folder and review the workflows that are currently scheduled.
The Guided Configuration’s Commit Configuration process may be used to schedule the Configurator Impact Analysis, Developer Impact Analysis and Security Impact Analysis workflows delivered with this release of LiveCompare. Results from these workflows will be listed in the Reports utility.
