Hi,

When I started to learn Salesforce I used my personal Salesforce Developer account to login and gain badges of Trailhead. Currently, I am employeed at a company which requested to gain Salesforce badges with my company e-mail. Is there a possibility to merge these accounts or explain Salesforce that the accounts belong to the same user and therefore the badges are interchangeable?

I hope there is a possiblity to avoid unnecessary work :)

Kind regards!
