you can specify the other name in "aliases" so it will know they're the same

then i think you do an up with no changes to fix the state and you can take it out

Thanks for your reply <@UEU2M37GX>. But that did not seem to work :disappointed:
1. Added alias "extgatewaya4f45d9d" as resourceopts
2. `pulumi up`
I get the same result:
```    ++azure:network/applicationGateway:ApplicationGateway: (create-replacement)
        [id=/subscriptions/*****/resourceGroups/*****/providers/Microsoft.Network/applicationGateways/extgatewaya4f45d9d]
        [urn=urn:pulumi:*****::*****::azure:network/applicationGateway:ApplicationGateway::extgateway]
        [provider=urn:pulumi:*****::*****::pulumi:providers:azure::default_2_1_0::]
      ~ name: "extgatewaya4f45d9d" =&gt; "extgatewayda1ac9a0"
    +-azure:network/applicationGateway:ApplicationGateway: (replace)
        [id=/subscriptions/*****/resourceGroups/*****/providers/Microsoft.Network/applicationGateways/extgatewaya4f45d9d]
        [urn=urn:pulumi:*****::*****::azure:network/applicationGateway:ApplicationGateway::extgateway]
        [provider=urn:pulumi:*****::*****::pulumi:providers:azure::default_2_1_0::]
      ~ name: "extgatewaya4f45d9d" =&gt; "extgatewayda1ac9a0"```

I guess this will be fine in this case, since its a `create-replacement`? So there will not be any downtime. But still little bit annoying.

hmm not sure then tbh that's worked for me
