• This is a bug with an existing resource and is not a feature request or enhancement. Feature requests should be submitted with Cloudflare Support or your account team.
• I have searched the issue tracker and my issue isn't already found.
• I have replicated my issue using the latest version of the provider and it is still present.

Terraform and Cloudflare provider version

Terraform v1.10.5
on linux_amd64
+ provider registry.terraform.io/cloudflare/cloudflare v5.1.0

Affected resource(s)

• cloudflare_list_item

Terraform configuration files

resource "cloudflare_list" "test" {
  account_id  = "..."
  name        = "test"
  description = "Test list"
  kind        = "redirect"
}

resource "cloudflare_list_item" "test" {
  account_id = "..."
  list_id    = cloudflare_list.test.id

  redirect = {
    source_url         = "https://test.example.com/"
    target_url         = "https://example.com/"

Panic output

No response

Expected output

Able to migrate cloudflare_list_item resource from v4 to v5, or use combination of terraform state rm / terraform import per the migration guide

Actual output

When doing a straight upgrade to v5:

Warning: Failed to decode resource from state
Error decoding "cloudflare_list_item.test" from prior state: missing expected {

Error: Resource instance managed by newer provider version
The current state of cloudflare_list_item.test was created by a newer provider version than is currently selected.
Upgrade the cloudflare provider to work with this state.

When attempting to remove and re-import the resource:

Error: Resource Import Not Implemented

Steps to reproduce

1. Create a cloudlfare_list_item resource under v4.52.0 of the provider
2. Upgrade to v5.1.0
3. Run terraform apply
4. Observe error above

Per other resources in the migration guide, the steps could look like

1. Run terraform state rm cloudflare_list_item.test
2. Upgrade to v5.1.0
3. Run terraform import cloudflare_list_item.test ...

But cloudflare_list_item does not support import in v5 of the provider. Is this intentional?
