How To Use Partitioned Domains in Non-Production Orgs?

To maximize the availability of your orgs, My Domain uses partitioned domains for new sandboxes, Developer Edition orgs, patch orgs, scratch orgs, and Trailhead Playgrounds.

Partitioned domains include a word related to the org type, which allows Salesforce to gradually roll out service delivery changes.

To ensure continued access to all your orgs, update your allowlists for the new domains.

To include your existing Developer Edition org in the Salesforce deployment schedule for that org type, enable partitioned domains.

Partitioned domains are enabled by default in new Developer Edition orgs, patch orgs, scratch orgs, and Trailhead playgrounds.

Sandboxes are partitioned if enhanced domains are enabled.

Partitioned domains allow Salesforce to gradually roll out service delivery changes by org type.

For example, Developer Edition orgs can get an update separately from production orgs.

This staggered approach maximizes the availability of production and sandbox orgs.

For example

The My Domain login URL format for a partitioned Developer Edition org is https://MyDomainName.develop.my.salesforce.com.

To ensure that your users can connect to partitioned domains, update your allowlists.

To partition an existing sandbox, enable enhanced domains.

In existing Developer Edition orgs, patch orgs, scratch orgs, and Trailhead Playgrounds with enhanced domains, you can enable or disable this feature from the My Domain Setup page.

When you change the Use partitioned domains option in the My Domain Details section, you can preview your new My Domain login URL at the bottom of the screen.

This option becomes available in demo orgs with enhanced domains when partitioning is available for that org type.
