Domain change, or community sub domain for those who already use Salesforce is not that straight foward. Therefore, there are few things you need to know before you actually enable it.
Step 1: Check your Salesforce edition
Before you start with the domain change, make sure that you have the required editions so that you will be able to change the domain.
|Available in: both Salesforce Classic and Lightning Experience|
|Available in: Essentials, Performance, Unlimited, Enterprise, Developer, Professional, and Group Editions|
Step 2: Check your permissions
|USER PERMISSIONS NEEDED|
|To define a domain name:||Customize Application, Modify All Data|
Step 3: When to change the domain
It is highly recommended that you change the domain outside of the business hours, because the change briefly interrupts your users work. Before the change of the My Domain subdomain, consider how to communicate with your users.
Step 4: Domain change
- From Setup, enter My Domain in the Quick Find box, then select My Domain.
- Under My Domain Settings, select Edit. Enter a new domain name.
- Select Check for availability, and if the domain is available, click Save.
