Allowing create and destroy before moving to the next target when running parallelism=1

[marcossegovia]

Is there an easy way that when running parallelism=1 terraform just destroy and create the current machine before jumping to the following target?
This will make me able to reprovision a whole stack (the stack is serving until the current machine is chosen to be reprovisioned) and not destroying all targets at the same time when reprovision.

Terraform Version

v0.11.7

Expected Behavior

vsphere_virtual_machine.assets[0] was destroyed
vsphere_virtual_machine.assets[0] start building
vsphere_virtual_machine.assets[0] finish building
vsphere_virtual_machine.assets[1] was destroyed
vsphere_virtual_machine.assets[0] start building
vsphere_virtual_machine.assets[0] finish building

Actual Behavior

vsphere_virtual_machine.assets[0] was destroyed
vsphere_virtual_machine.assets[1] was destroyed
vsphere_virtual_machine.assets[0] start building
vsphere_virtual_machine.assets[0] finish building
vsphere_virtual_machine.assets[1] start building
vsphere_virtual_machine.assets[1] finish building

Steps to Reproduce

When trying to reprovision 2 machines by the following command:

terraform apply -target="vsphere_virtual_machine.assets[0]" -target="vsphere_virtual_machine.assets[1]" -parallelism=1

Hi @marcossegovia,

It sounds like you're looking for a "rolling update" feature, which we're tracking in issue #16378.

Using -parallelism=1 is not meant to do this, as that will only allow a single resource to be updated at a time, but does not alter the dependency graph for the operations.
