I'm upgrading the Liferay theme from 7.1 to 7.2. I followed this documentation up to step 2. Step 3 fails as 'gulp upgrade' command throws the following exception. 
>gulp upgrade

fs.js:33
} = primordials;
    ^ReferenceError: primordials is not defined

Hi Vishnu, this is likely the result of a gulp and node combination. I replied to this topic in the past:  https://liferay.dev/forums/-/message_boards/message/117746802/maximized#_com_liferay_message_boards_web_portlet_MBPortlet_message_117790975 but I can also add https://stackoverflow.com/questions/55921442/how-to-fix-referenceerror-primordials-is-not-defined-in-node and https://github.com/liferay/clay/issues/2053.
So either upgrading to gulp 4 or downgrading to an earlier node version should help.

Thank You. You're right. It has caused due to the node and gulp combination. However, upgrading gulp to v4 didn't work with any versions of the node. After a few experiments, I figured out the working combination. node v11.15.0 and gulp v3.9.1.
