XF 2.3 CLI upgrade of addons from XF1 to XF2.3

[Alpha1]

I'm doing some test runs of the upgrade of my big board. I have many addons, including some very large ones. Upgrading these manually is taking a loooong time.

Is there a way to use CLI to upgrade a batch of addons? And if not, then is it possible to CLI upgrade addons one by one?
I could not find any information on CLI upgrade of addons in the XF manual.
What command should I use?

@Xon do you still have a script for this?

I actually have a tiny add-on which implements a php cmd.php addon:upgrade-pending --include-legacy command, which is designed for batch updates but I'll need to check what is outstanding blocking it being released.
