I am using the Azure Portal to move a Resource Group from one subscription to another one. During the validation phase, it complains about a public IP address in the resource group, which cannot be moved. That's alright, I do not mind if the IP changes and I get a new one after the move. The question is how to drop the public IP without losing the configuration for the other resources that depend on it, and then how to re-add a new IP address after the move and get it linked instead of the old one. The IP address is associated to a network interface in a virtual machine and there is a network security group controlling the ports that are open.

Hi @Alberto Poblacion Are you trying to move to a resource group in another region? Azure Public IPs are region specific and can't be moved from one region to another. You can however, use an Azure Resource Manager template to export the existing configuration of a public IP. reference: https://learn.microsoft.com/en-us/azure/virtual-network/move-across-regions-publicip-portal if in the same region, subscriptions must be in the same tenant: reference: https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/move-resource-group-and-subscription#checklist-before-moving-resources Get in touch if you need more help with this issue. --please don't forget to " Accept the answer " if the reply is helpful--

@ Jackson Is it possible to move static Public IPs to another Azure Subscription in the same Azure Region and Azure Tenant?

If you click "Disassociate" on the IP-resource first, the move-operation should work.

Hi @Alberto Poblacion

Azure Public IPs are region specific and can't be moved from one region to another. You can however, use an Azure Resource Manager template to export the existing configuration of a public IP.

if in the same region, subscriptions must be in the same tenant:

No, no. I am not trying to move to a different region. It is a different subscription, but I want to keep all the resources in the same region.

And I don't care about moving the IP. It's o.k. if it is lost and I have to assign a new one in the target subscription. My problem is that I do not know how to move everything else. The Portal does not allow me to continue because other resources have dependencies on the IP. So I wanted to find out how I can remove the IP without losing anything else, move all the other resources without losing their configuration, and then assign a new IP after the move is done.

Virtual machines in an existing virtual network can be moved to a new subscription only when the virtual network and all of its dependent resources are also moved, so, you can create a new VNET and a new interface to use this vnet.
After creating new vnet, you can migrate all content to new subscription.

Probably your ip or vnet is being used for other resources, so I suggested creating a new vnet and migrating all the content

Thank you for the link that you provided. It explains why I couldn't find the option in the portal; according to the document, you can only add or remove nics to the VM through the command line.
I'm sure that the IP is not being used by anything else. My plan is to add to the VM another nic, not connected to a public IP, then remove the connected NIC, then move the whole set to the other subscription, and then add a public IP to the NIC once it is in the new subscription. I hope I will be able to figure out all the steps. Ideally, there should be better support under the "move" option in the portal to make these things easier.
