Description

Currently it's not possible to configure or update the target VM SKU on azurerm_site_recovery_replicated_vm. If the SKU on Source VM is changed, it gets updated in the Source settings but not on the Target settings. Only recreating the whole replication will update the Target settings.

But it is possible to update the Target settings via Azure Portal or Azure ARM API -> recoveryAzureVMSize.

Configuring the recovery VM Size should also be possible via azurerm_site_recovery_replicated_vm
