NXPowerLite for File Servers v9 installation and data migration

To make for easier adoption of NXPowerLite for File Servers 9, we have included a feature that will migrate your existing v8 configuration and data from version 8. There are a few things to note and the details of these are below.

Migration parameters

  • Migration only works from v8 to v9 of NXPowerLite for File Servers. Contact us for advice on how to migrate v7 settings.
  • The actual migration event happens when the new version of the software is registered. Any settings applied when v9 is in Evaluation mode will be lost.

Specific configuration migrated

The following configuration settings will be migrated and appear in the new software:

  • Included and excluded folders including any applied rules
  • ‘Optimization settings’ profiles
  • ‘Files to include’ profiles
  • Scheduling profiles
  • Preferences
  • Live reports
  • Historical reports
  • Custom registry settings

Considerations before running v9 after migration

NXPowerLite for File Servers includes changes to existing features and new optimization settings. These change the compression applied to files and are enabled by default in any migrated Optimization setting profile. In particular, we would draw your attention to the following settings which change existing compression behavior, and if required, can be disabled in Optimization settings profiles.

Flatten embedded objects in PPTX and DOCX.

When flattening charts in PPTX and DOCX, NXPowerLite V9 will remove the embedded XLSX file containing the chart data and retain only the data required to display the chart.

Delete cropped areas of images

This setting now works in PPTX files. Previously it only worked in Office binary formats (PPT, DOC, and XLS)

Reduce the color depth of PNG images in Office files

This is a new setting that is enabled by default.

Subset Embedded fonts in PDF

This is a new setting that is enabled by default.

Configuration not migrated

Windows service user account configured

It is not possible to maintain the configured user account that the NXPowerLite for File Servers Windows service uses. This will need to be reconfigured after the installation of v9. See Configuring the NXPowerLite Windows Service for more details.

History of files processed files stored to speed up overall compression

In order to take advantage of the improved compression in the latest software, it is necessary to try to compress files previously compressed by NXPowerLite. Also, some files that previously failed to compress will be able to compress.
For this reason, the database used to store the history of files processed by NXPowerLite will not be migrated. This means the software will most likely appear to be slower in the first runs, however, it also means it is likely to get better compression of new and existing files.

Current day's reported results data

It was not technically possible to migrate reported results data since midnight the night on the day of registration. To ensure all reported data is transferred, stop NXPowerLite v8 and leave 24 hours before installing v9.

Migration failure

In the unlikely event that migration fails the software will enter a fatal error state and will not allow access to the Dashboard. Follow the steps detailed below to retry migration and if this process fails, contact us.

If migration fails, the Application event log (which can be viewed using the Windows Event Viewer) will contain a recent error event from NXPowerLite for File Servers, with event ID 2088. If this is not the case, contact us for assistance.

  • Uninstall NXPowerLite for File Servers v9.
  • Using Registry Editor, delete the Registry key
  • HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Neuxpower\NXPowerLite Fileserver\9.0 (on 32-bit
