Upgrading Qlik NPrinting

You can upgrade from Qlik NPrinting 17.3.0 or later to Qlik NPrinting June 2017 or later using the Qlik NPrinting setup program. When upgrading, the previous version is completely replaced by the new version.

Configuration files

The content of the following files is overwritten during the upgrade process:

• NewsStand proxy configuration file

  %ProgramFiles%\NPrintingServer\proxy\newsstandproxy\src\qlik.com\newsstandproxy\conf\app.conf

• Qlik NPrinting web console proxy configuration file

  %ProgramFiles%\NPrintingServer\proxy\webconsoleproxy\src\qlik.com\webconsoleproxy\conf\app.conf

If you have made custom configurations in either of these files in your existing Qlik NPrinting deployment, you must recreate them manually after an upgrade.

When you upgrade to Qlik NPrinting June 2017 or later the following new folders are created automatically:

• %ProgramData%\NPrinting\newsstandproxy\
• %ProgramData%\NPrinting\webconsoleproxy\

A copy of the app.conf file, with everything commented, is inserted in each folder. Settings that are not commented in the app.conf files have a higher priority than the old files, so they will overwrite the same settings in the older files. After the first upgrade the settings in the new app.conf files will be kept.

Upgrading

Do the following:

1. Confirm that you have a current backup of the repository.
   Warning: You must back up your data before you continue. Data can be damaged if a problem occurs during the upgrade, so it is necessary to have backup to restore the repository from . See Backup and restore a repository.
2. Open Windows Services.
3. Stop the following Qlik NPrinting services by right-clicking them, and then clicking Stop:

4. Close Windows Services.

   Windows stops the services only after you close this program, so do not keep it open.

Warning: Proceed only when you are sure that all the services mentioned are stopped or the repository may be damaged. If any of these services are left running during upgrade, the upgrade can fail, and it may be necessary to restore data from backup.
