<div style="background:#eee;border:1px solid #ccc;padding:5px 10px;">xe host-call-plugin plugin=prepare_host_upgrade.py host-uuid=750d9176-6468-4a08-8647-77a64c09093e fn=testUrl args:url=http://<ip-address>/xcp/</div> 
The returned output must be&nbsp;'''true'''&nbsp;to continue.

Now tell the host to automatically boot to the ISO and upgrade itself on next reboot (using the UUID and URL from before):
<div style="background:#eee;border:1px solid #ccc;padding:5px 10px;">xe host-call-plugin plugin=prepare_host_upgrade.py host-uuid=750d9176-6468-4a08-8647-77a64c09093e fn=main args:url=http://<ip-address>/xcp/</div> 
&nbsp;

The output should also be&nbsp;'''true'''. It has created a temporary entry in the grub bootloader which will automatically load the upgrade ISO on the next boot. It then automatically runs the XCP-NG upgrade with no user intervention required. It will also backup your existing XenServer dom0 install to the secondary backup partition, just like the normal upgrade.

To start the process, just tell the host to reboot. It is best to watch the progress by using KVM if it’s available, but if not, it should proceed fine and boot into upgraded XCP-NG in 10 to 20 minutes.
