Hi Daniel, In general your VR template is governed by the global setting for router.template.vmware (or whatever your hypervisor is) – this field is updated when you do your upgrade, so ACS knows what the new template is.
To do the upgrade your easiest option is to use CloudMonkey and call the upgradeVirtualrouterTemplate API call from command line. Something like “cloudmonkey upgrade virtualroutertemplate account=XYZ zoneid=aa-bb-cc-dd podid=aa-bb-cc-dd id=123123” etc should do it – refer to the API documentation page you have found. As always though I would recommend testing this beforehand in a non-prod environment. With regards to your GUI options – are you using CloudStack or CloudPlatform? (The shadow mode is not a feature of Apache CloudStack at this point).

I wrote a python script to check VPN connections and other parameters. Some upgrades can be performed right after the CP upgrade, some other routers must not be upgraded, as those will be upgraded manually after some more coordination. Now I am struggling how to upgrade the Routers using the API. I found the command “upgradeRouterTemplate“ (https://cloudstack.apache.org/api/apidocs-4.5/root_admin/upgradeRouterTemplate.html), which, when I understand it correctly, should support that. However, when upgrading using the GUI I can select both the SystemVM Template and opt to use a shadow mode. The command mentioned above however does not allow me to specify those arguments. So my question is: what would be the best way to upgrade the routers using the API?
