1. Run the file nexus-timestamp-installer-2.2.0.jar and follow the instructions.
2. During the upgrade:
   1. On Windows
      The installer will automatically detect an existing Nexus Timestamp Server installation from the Windows registry and upgrades your Nexus Timestamp Server files and libraries located in the <install> directory (default C:\Program Files\Nexus\Timestamp Server).
   2. On Linux
      The installer will only detect an existing Nexus Timestamp Server installation if the selected install path already contains an existing Nexus Timestamp Server installation. If detected, the installer will upgrade the files and libraries located in the <install> directory (default /usr/local/timestamp-server).
      
      After the upgrade is complete you MUST re-configure the service user defined in <install>/bin/timestamp-server.conf by adding a line containing SERVICEUSER=theuser.

New functionality

New functionality in the configuration files is described in the release note. If you want to use the new functionality, you must manually update the configuration files.

The configuration files are located here:

• On Windows: C:\ProgramData\Nexus\timestamp-server\conf
• On Linux: /etc/timestamp-server

Mandatory updates

Do these mandatory updates in the configuration files:

1. The java logging configuration has changed. If your logging.properties file is unchanged this is handled automatically by the upgrade process. Otherwise replace your logging.properties file with the new default configuration (see below) and adapt it to your preference:
   

   Configuration change for java logging

   	#
       # configuration for logging
       #
       handlers = com.id2tech.logging.TimeRollingFileHandler
   
       # Dependencies should log on Warning
       .level = WARNING
       # Nexus classes should log on Info
       se.nexus.level = INFO
       com.id2tech.level = INFO
       com.nexussafe.level = INFO
       nano.audit.level= INFO
   
       com.id2tech.logging.TimeRollingFileHandler.pattern = %5$s/logs/%ty-%<tm-%<td/timestamp.log
       com.id2tech.logging.TimeRollingFileHandler.level = INFO
       com.id2tech.logging.TimeRollingFileHandler.formatter = com.id2tech.logging.OneLineMessageFormatFormatter
   
       #java.util.logging.ConsoleHandler.formatter = com.id2tech.logging.OneLineMessageFormatFormatter
       #java.util.logging.ConsoleHandler.level = FINEST

   
   

2. Parameter change in timestamp.properties. If your timestamp.properties file is unchanged this is handled automatically. Otherwise do the following:
   

   1. Replace

      #include ./server-0/*-webapp.properties

      with

      #include ./server-0/front-webapp.properties

   2. Replace

      #include ./server-1/*-webapp.properties

      with

      #include ./server-1/admin-webapp.properties
      
      #include ./server-1/root-webapp.properties

   3. If more #include parameters are present, do the same change for them.

New functionality

New functionality in the configuration files is described in the Release note (LINK). If you want to use the new functionality, you must manually update the configuration files.

The configuration files are located here: 

• On Windows: C:\ProgramData\Nexus\timestamp-server\conf
• On Linux: /etc/timestamp-server

Mandatory updates

Do these mandatory updates in the configuration files:

1. Configuration change for ClockFilter, see Description of filters in Nexus Timestamp Server, heading "ClockFilter".

   1. Reason: changed name from GlobalClockFilter to ClockFilter.

   2. Change the line 'class=com.nexussafe.nano.filters.GlobalClockFilter' in service.properties, to:

      Configuration change for "ClockFilter"

      class=com.nexussafe.nano.filters.ClockFilter

2. Configuration change for filter.OcspValidator, see see Description of filters in Nexus Timestamp Server, heading "validation.OCSPValidationFilter".
   1. Reason: changed 'ocsp.signRequest' parameter value for the OCSPValidator.

   2. If applicable, change the parameter value of 'ocsp.signRequest'  from 'yes/no' to 'true/false' in service.properties.

It is not possible to upgrade a current Nexus Timestamp Server 1.x installation to Nexus Timestamp Server 2.2.0.

Instead do the following:

1. Back up the configuration and logs for your Nexus Timestamp Server 1.x installation.
2. Uninstall Nexus Timestamp Server 1.x.
3. Install Nexus Timestamp Server 2.2.0 (see Install and upgrade Nexus Timestamp Server) and adapt the configuration. Configuration file names and parameters have changed.
