+page_title: "Migrating dedicated servers from previous versions to v2.2.0"
+---
+
+Version v2.0.0 of OVHcloud Terraform provider introduced a breaking change on the resources related to dedicated servers, mainly:
+- Deletion of resource `ovh_dedicated_server_install_task` that has been replaced by a new resource `ovh_dedicated_server_reinstall_task`
+- The parameters of resource `ovh_dedicated_server` have been updated to reflect the changes on parameters needed to reinstall a dedicated server
+
+The complete changelog can be found [here](https://github.com/ovh/terraform-provider-ovh/releases/tag/v2.0.0).
+
+This guide explains how to migrate your existing configuration relying on resource `ovh_dedicated_server_install_task` to a new configuration compatible with version v2.2.0 of the provider without triggering a reinstallation of your dedicated servers.
+
+!> This documentation presents a direct migration path between v1.6.0 and v2.2.0. To make this transition easier, we released a version v1.8.0 of the provider that includes both deprecated resources and the new ones. The migration steps are the same, but this version allows a more gradual shift towards v2.2.0.
+
+## First step: import your dedicated servers in the state
+
+From version v2.0.0 and later, the preferred way to manage dedicated servers installation details is through usage of resource `ovh_dedicated_server`. As a result, if you don't already have your dedicated servers declared in your Terraform configuration, you must import them.
+
+You can use an `import` block like the following:
+
+```terraform
+import {
+  id = "nsxxxxxxx.ip-xx-xx-xx.eu"
+  to = ovh_dedicated_server.srv
+}
+
+resource "ovh_dedicated_server" "srv" {}
+```
+
+-> If you are doing a first migration to v1.8.0, you should add the following parameter `prevent_install_on_import = true` to the dedicated server resource. This guarantees you that the server won't be reinstalled after import, even if you have a diff on the reinstall-related parameters.
+
+To finish importing the resource into your Terraform state, you should run:
+
+```sh
+terraform apply
+```
+
+## Second step: backport your previous task details into the imported resource
+
+This step is manual and requires you to convert the previous installation details from resource `ovh_dedicated_server_install_task` to the new fields of resource `ovh_dedicated_server`: `os`, `customizations`, `properties` and `storage`.
+
+Let's take an example: if you previously used the following configuration:
+
+```terraform
+resource "ovh_dedicated_server_install_task" "server_install" {
+  service_name      = "nsxxxxxxx.ip-xx-xx-xx.eu"
+  template_name     = "debian12_64"
+  details {
+      custom_hostname = "mytest"
+  }
+  user_metadata {
+    key = "sshKey"
+    value = "ssh-ed25519 AAAAC3..."
+  }
+  user_metadata {
+    key = "postInstallationScript"
+    value = <<-EOF
+        #!/bin/bash
+          echo "coucou postInstallationScript" > /opt/coucou
+          cat /etc/machine-id  >> /opt/coucou
+          date "+%Y-%m-%d %H:%M:%S" --utc >> /opt/coucou
+        EOF
+  }
+}
+```
+
+You can replace it by the following one:
+
+```terraform
+resource "ovh_dedicated_server" "srv" {
+  customizations = {
+    hostname                 = "mytest"
+    post_installation_script = "IyEvYmluL2Jhc2gKZWNobyAiY291Y291IHBvc3RJbnN0YWxsYXRpb25TY3JpcHQiID4gL29wdC9jb3Vjb3UKY2F0IC9ldGMvbWFjaGluZS1pZCAgPj4gL29wdC9jb3Vjb3UKZGF0ZSAiKyVZLSVtLSVkICVIOiVNOiVTIiAtLXV0YyA+PiAvb3B0L2NvdWNvdQo="
+    ssh_key                  = "ssh-ed25519 AAAAC3..."
+  }
+  os         = "debian12_64"
+  properties = null
+  storage    = null
+}
+```
+
+You can check the documentation of resource `ovh_dedicated_server` to see what inputs are available for the reinstallation-related fields.
+The documentation of resource `ovh_dedicated_server_reinstall_task` also includes several examples of configuration.
+
+## Third step: make sure your server is not reinstalled unintentionally
+
+You should add the following piece of configuration in the declaration of your dedicated server resource in order to avoid a reinstallation on the next `terraform apply`:
+
+```terraform
+resource "ovh_dedicated_server" "srv" {
+  #
+  # ... resource fields
+  #
+
+  lifecycle {
+    ignore_changes = [os, customizations, properties, storage]
+  }
+}
+```
+
+This is needed because there is no API endpoint that returns the previous installation parameters of a dedicated server. The goal here is to migrate your old configuration to the new format without triggering a reinstallation.
+
+## Fourth step: remove the lifecycle block
+
+After a while, whenever you need to trigger a reinstallation of your dedicated server, you can just remove the `lifecycle` field from your configuration and run `terraform apply`.
