1. Go to the Flow installation directory. This is usually the home directory of the Linux user that runs Flow and it should contain a directory named "partek_flow". The location of the Flow install can also be obtained by running ps aux | grep flow and examining the path of the running Flow executable.
   
   
2. Shut down Flow: ./partek_flow/stop_flow.sh
   
   

3. Download the new version of Flow and the Flow worker from the link Partek support send (below is an example of the links): 
   

   wget http://www.partek.com/PartekFlow-RemoteWorker-current-version.zip

   wget http://www.partek.com/PartekFlow-LINUX-current-version.zip

    

4. Make sure Flow has exited:
   ps aux | grep flow
   The flow process should no longer be listed.
   
   
5. Unpack the new version of Flow install and backup the old install:
   mv partek_flow partek_flow_prev
   mv PartekFlowRemoteWorker PartekFlowRemoteWorker_prev
   
   
6. Backup the Flow database folder. This should be located in the home directory of the user that runs Flow.
   tar -czvf partek-db-bkp-date.tgz ~/.partekflow
   
   
7. Start the updated version of Flow:
   ./partek_flow/start_flow.sh
   tail -f partek_flow/logs/catalina.out (make sure there is nothing of concern in this file when starting up Flow. You can stop the file tailing by typing: CTRL-C)
   
   

   You may also want to examine the the main Flow log for errors:

   ~/.partekflow/logs/flow.log
