Migration of iaas resources from openstack provider

[hown3d]

Problem description

With the deprecation of the openstack API in STACKIT a lot of people might still use the openstack terraform provider to manage IaaS resources on STACKIT. Terraform provides a moved block that can be used to move state from one resource to another. I would like to define my terraform resources with the new IaaS API resources and use a moved block to move the state from the Openstack resources to the new IaaS API ones.

Proposed solution

I would expect e.g. these resources to support such a migration

• openstack_compute_instance_v2 => stackit_server
• openstack_networking_network_v2 => stackit_network
• openstack_networking_port_v2 => stackit_network_interface
• openstack_networking_floatingip_v2 => stackit_public_ip
• openstack_networking_secgroup_v2 => stackit_security_group
• openstack_networking_secgroup_rule_v2 => stackit_security_group_rule
• openstack_blockstorage_volume_v3 => stackit_volume

resource "openstack_compute_instance_v2" "basic" {
  name            = "basic"
}

resource "stackit_server" "basic" {
  project_id   = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
  name         = "basic"
}

moved {
  from = openstack_compute_instance_v2.basic
  to = stackit_server.basic
}

Additional information

The terraform-plugin-framework provides an interface on how to implement the move for such resources: https://developer.hashicorp.com/terraform/plugin/framework/resources/state-move

Since this is an already open issue it would be also great to have the same features like explained in https://github.com/stackitcloud/terraform-provider-stackit/pull/476. Currently there is no way to get the stackit_network from a data source by name. This is probably the case for other resources too. I could also create an additional Feature Request for that if its needed

Hi @hown3d, thank you for reporting this issue. We will have a look at it.
