Move the Primary Server to Another Host

  1. Stop Exalead CloudView.
  2. Copy the <DATADIR> to the new host.
  3. If running as a Windows service, unregister it: 

    bin\unregisterservice.exe

  4. (Optional) If running a multihost install, stop Exalead CloudView on all hosts.
  5. On the new host, unzip the same kit that was used on the previous host.
  6. On the new host, verify that the installation is OK by running:

    ./install.sh or install.bat without any arguments.

  7. Edit the file $DATADIR/bin/ngstart.env and update the following:
    • NGHOSTNAME – specify the name of the new host.
    • NGINSTALLDIR – specify the place on the new host where you unzipped the kit.
    • (Optional) If their paths to the new ${NGDATADIR} have changed, edit NGRUNDIR, NGCONFIGDIR, and CVLICENSE.
    • NGGATEWAYHOSTPORT
  8. Edit config/Deployment.xml and update the hostname to match the NGHOSTNAME that you specified in the previous step.
  9. Force a manual configuration update by running: bin/buildgct.
  10. If running as a Windows service, register it again: bin\registerservice.exe.
  11. Start the product.
  12. (Optional) If running a multihost install, for each slave:
    1. Edit bin/ngstart.env
    2. Modify NGGATEWAYHOSTPORT.
