Generate page.module.ts files in iOnic 2 project

The iOnic Team published an iOnic 3 BETA upgrade guide with a special command to generate the page.module.ts files in an iOnic 2 project for iOnic 3.0 migrations.
In the updated guide for iOnic 3.0 final, they removed the command.

Did anybody remember this command?

Did they maybe just use ionic g page pagename?
(If it was in Google Docs, is the revision history accessible in the document?)

No there was an npm command to generate the modules for existing pages.

I can’t find the old “Upgrade to iOnic 3 Beta” Google Doc. They removed it by the Stable iOnic 3 upgrade guide
