What steps do I need to take if I want to switch my G Suite domain and continue using the same Zendesk instance?
- Remove the external support address associated with the first G Suite account in your email settings. Go to Admin > Channels > Email to delete the external support address.
- Disconnect the email routing associated with your Zendesk account in G Suite. Go to the Forwarding and POP/IMAP page in Settings to delete forwarding addresses.
- Set up the email routing. Here's the link to forwarding steps for G Suite Route users’ email to another address.
It’s actually about changing the SSO, so all your agents log in with their new email addresses (so you don’t lose access with the email address still being the old one for your agent login).
