Guide on how to Migrate Pulumi Backend from default local file, e.g. to https://api.pulumi.com

[ceefour]

Webiny by default uses Pulumi local backend.

I have tried following the guide in https://www.pulumi.com/docs/intro/concepts/state/#migrating-between-backends with a bit of modification (https://about.lovia.life/docs/engineering/webiny/).

However, webiny still insists on using local Pulumi backend:

# set PULUMI_ACCESS_TOKEN=.............

D:\project_win\lovia\lovia-webiny>yarn webiny pulumi api --env=dev -- logout
webiny info: Environment provided - selecting dev Pulumi stack.
webiny info: Running the following command in api folder:
webiny info: pulumi logout

D:\project_win\lovia\lovia-webiny>yarn webiny pulumi api --env=dev -- login https://api.pulumi.com     
webiny info: Environment provided - selecting dev Pulumi stack.
webiny info: Running the following command in api folder:
