Version Control #
A version control system helps manage the data transfer from test environment to production environment by keeping track of all modifications.
Git or Azure DevOps are version control systems that can be used to ensure:
- The deployment of new extractions, sources and destinations can not cause fundamental damage to the data load of the productive landscape.
- User rights and other features allow for changes to be checked and corrected in advance.
- Quick and easy rollbacks of changes.
For more information on how to set up version control with Xtract Universal, refer to the knowledge base article Deploying Extractions Using Git Version Control.
Configuration Files #
All configuration files of extractions, sources, destinations and the server are stored in the sub-directory
config of the Xtract Universal program directory, e.g.,
config directory for setting up a version control system or creating manual backups.
||Directory containing the destinations. Each
||Directory containing the extractions. Each sub-directory contains an extraction of the same name.|
||Directory containing the server settings.|
||Directory containing SAP connections. Each sub-directory contains a source of the same name.|
||Text file containing the product version of the current configuration. See also New Installation and Update.|
Manual Backups #
Recommendation: Make sure to create regular backups of the configuration files to save the work invested in designing and optimizing your data extraction processes.
A backup allows you to easily switch back to the previous product version, if needed. See also section Installation and Update.
How to Create a Backup
- Copy the complete
C:\Program Files\XtractUniversal\configby default) of the machine running the Xtract Universal Service and store the files in safe and secure locations.
- Optional: copy the complete
C:\Program Files\XtractUniversal\logsby default) to create a backup of the log files.
- To backup your license, create a copy of your
Warning! Data security.
logs directories may contain sensitive information.
How to Restore a Backup
- To restore the configuration files, remove the
configdirectory from the program directory (
C:\Program Files\XtractUniversalby deafult) of the machine running the Xtract Universal Service.
- Copy the backup of the
configdirectory into the program directory.
- To restore the license, replace the
XtractUniversalLicense.jsonfile within the program directory with the backup.
Warning! Data Loss!
Restoring the backup of the
config directory replaces the exisiting configuration. Make sure to remove the existing files before restoring the backups.
Manual Migration to a Different Machine #
Configuration files can be migrated partially or entirely (full migration).
Depending on your scenario it can make sense to conduct a partial migration - e.g., if you transport extractions from a test to a production environment. When replacing a machine completely, conduct a full migration.
Note: When migrating to a new server, a new license file must be issued for that server. Contact our sales team at email@example.com for more information.
The same Xtract Universal versions must be installed on both machines.
To install the matching version on the different machine, use the
XtractUniversalSetup.exe from the program directory (
C:\Program Files\XtractUniversal) of the current machine.
To check the version of your product, open the Designer and navigate to Help > Info or press [F12].
How to Migrate
- Create a backup of the
configdirectory of the current machine. The default directory of the
- Decide whether you need a partial or a full migration.
For a full migration restore the entire
configdirectory on the different machine.
For a partial migration restore parts of the backup, by copying subfolders from the
configdirectory, e.g., only destination or extraction directories. When copying single
version.txtfile must be copied, too. The
version.txtis located in the
- Restart the Xtract Universal Service, when performing a full migration or copying the
serverdirectory onto the different machine.
Note: As of Xtract Universal version 5.0 SAP passwords are encrypted with a key that is derived from the Windows account that runs the XU service. The passwords can only be accessed from the same service account, when restoring a backup or moving the files to a different machine. If the service account changes, passwords need to be re-entered manually.
