Cannot Put the Read Replica in different resource group to master server

[archmangler]

It appears that it's not possible to create a read replica in a different resource group to the master postgres instance.

This is unfortunate because it reduces the resilience of the postgres deployment: if the resource group is accidentally deleted we lose both the primary postgres server and the read replicas at one time.

Is this correct? If not , how can a read replica be deployed in a separate resource group and region to the primary?

You can create the replica and then use the Move button in resource group level to move a replica to another resource group

You can also use a resource lock to prevent accidental deletion of resources https://docs.microsoft.com/azure/azure-resource-manager/resource-group-lock-resources
