This section provides information on upgrading from your current version to a later version of NPKD.
Upgrading to NPKD 1.6.1 from NPKD 1.4.x or older versions are no longer supported. If upgrading from NPKD 1.4.x or older versions, you need to upgrade to an intermediate version first.
Follow the steps below to upgrade NPKD to a new version.
We recommend making a full database backup before upgrading NPKD.
Unpack the NPKD Release Package
Unpack the release ZIP file on the server using the
unzip command. This creates a new folder called
npkd-X.Y.Z, where X.Y.Z is the version number. Adjust the paths as needed to match the installation directory.
unzip -q npkd-X.Y.Z.zip -d /opt/primekey/
If you use a symbolic link to reference NPKD, ensure to update it:
ln -snf /opt/primekey/npkd-X.Y.Z /opt/primekey/npkd
Copy the Existing Configuration
Copy the existing configuration, in the
conf directory, from the previous version to the new version. Adjust the paths in the command.
cp /opt/npkd-OLD/conf/*.properties /opt/npkd-NEW/conf/
Review Release Notes
Upgrades to certain versions may introduce changes that are important to be aware of and may require additional upgrade steps to be taken.
For important information to be aware of when upgrading from an earlier version of NPKD, ensure to review the NPKD Release Notes before upgrading (also available in your NPKD release folder under
Check Database Upgrade Script
Check if there are relevant upgrade scripts in
doc/sql-scripts. The scripts are named
upgrade-OLD-to-NEW.sql, where NEW is the new version and OLD is the preceding version.
If you did not already run the scripts, do it now. Use the following syntax:
mysql DB-NAME -u DB-USERNAME -p < doc/sql-scripts/upgrade-OLD-to-NEW.sql
Ensure to run all relevant upgrade scripts, if there is more than one since the existing version, and in the correct order
Deploy the New Version
NPKD releases come with pre-built binary code, so no compilation is required. Using the
ant tool, it is possible to build and deploy a software package to the application server.
Use the following command to build and deploy NPKD:
Restart the Application Server
As a final step, please restart the application server and wait for it to start up.
