Upgrading or downgrading vSLX (host installation)

Use this task to uninstall a vSLX host-installation—preserving your vSLX objects and configurations—and reinstall a different vSLX version.

Note

This flow installs new vSLX and SLX-OS versions—while maintaining support for existing and new objects of currently installed SLX-OS versions. But if you need a clean upgrade, refer to Uninstalling vSLX completely.

1. In vShell, make sure that all devices (chassis and workstations) are powered off.
   

   (vsh) poweroff ch_9540_01

2. Make sure that any host VMs are closed.
3. Uninstall the current vSLX distribution—preserving your vSLX objects and configurations.
   

   user@ubuntu:~$ sudo dpkg -r vslx

4. Enter the dpkg -i command, specifying the new vSLX package.
   

   user@ubuntu:~$ sudo  dpkg -i vslx_x.x.x.deb

5. Enter the postinst-setup.sh command, specifying the new post-installation package.
   

   user@ubuntu:~$ sudo /VM/postinst-setup.sh

6. Reboot the server.
   

   user@ubuntu:~$ sudo reboot
