Introduction

As part of the forthcoming Salesforce Spring ‘23 release, it has been announced in advance that Enhanced Domains will be auto enabled. What does this mean for Salesforce customers? Why should you care? It will just work….right?

Who is affected?

When you login to your production org you are probably already seeing a message like the one below:

Have you clicked the link, do you understand what might be the impacts and how you should prepare?

When does this affect me?

The overall release calendar released by Salesforce is as per the graphic below:

The date you need to start testing Enhanced Domains is when Sandbox Preview starts on Jan 6th 2023 and finish before your production org is upgraded, but you can already switch this feature on manually to get ahead of the game! To check if there is an impact enter Setup-> My Domain and check the message as the example below:

OK, but what is Enhanced Domains?

Enhanced domains change URLs formats across your org, this can cause integrations in particular to break and if your current test automation solution isn’t from Provar you may find those solutions impacted too.

What does this change?

When you deploy enhanced domains, all URLs across your org contain your company-specific My Domain name, including Experience Cloud sites and Salesforce sites. Here are some example URL formats for a production org with enhanced domains.

TYPEENHANCED DOMAIN URL FORMAT
LoginMyDomainName.my.salesforce.com
Experience Cloud sitesMyDomainName.my.site.com
Salesforce SitesMyDomainName.my.salesforce-sites.com
Visualforce pagesMyDomainName–PackageName.vf.force.com
Sandbox LoginMyDomainName–SandboxName.sandbox.my.salesforce.com
Experience Cloud sites in a sandbox orgMyDomainName–SandboxName.sandbox.my.site.com

What is most likely to break?

It’s a wide spectrum but thankfully shallow. You may see some of the items below fail silently or give errors, this is not an exhaustive list but indicative of things to check:

  • Connected App URLs and SSO settings (especially values outside of Salesforce, such as in Google Apps or External SSO Config)
  • Custom Apex, Aura and LWC code with hard coded URLs
  • Custom formula fields or links with hard coded full URLS instead of relative URLs
  • Experience Cloud and Salesforce Sites links (both internal and inbound external links to public site content)
  • Named Credentials
  • URL values in Custom Metadata records and Custom Settings
  • CTI Integration
  • Publicly accessible images
  • Other 3rd party or custom integrations relying on the standard salesforce URLs

It’s probably also a good time to check your Installed Packages and whether there are updates from the vendors you should be planning for to resolve any known issues with their app and Enhanced Domains.

How can I test this?

If you already have a Provar Automation test project follow these steps:

  1. Check you have sufficient test coverage, especially for the end to end scenarios above. Integration is more likely to ‘fail silently’ so you need to be asserting expected results of your integration where possible
  2. Ensure you have a free Sandbox with published sites, Experience Clouds and working integrations. Not everyone has the luxury of a complete end-to-end pre production or staging environment but this is incredibly valuable for all quality assurance purposes.
  3. Enhanced Domains should be enabled automatically since Winter ‘23 or follow the Enable Enhanced Domains as instructed by Salesforce, including My Domain setup if required
  4. Run your end-to end Provar regression test plan and review the results, and don’t panic

The plus side of all this is these changes by Salesforce will protect you from having to repeat this exercise at shorter notice if in the future your org is migrated to a new pod, something Salesforce now do regularly as part of their infrastructure replacement process and migration from dedicated datacenters to Hypercloud.

This is terrible, everything is broken, help!

Don’t panic! Firsty there  is an opt out up until Winter ‘24. Read more at: https://help.salesforce.com/s/articleView?id=sf.domain_name_enhanced_enable.htm 

At the time of writing this states:

“Salesforce enforces enhanced domains in all orgs in Winter ’24. To help you test, Salesforce deployed this feature in sandbox and non-production orgs with Winter ’23. Non-production orgs include sandboxes, demo orgs, Developer Edition orgs, free orgs, patch orgs, Trailhead Playgrounds, and trial orgs. Salesforce deploys this feature in all orgs with Spring ’23 and Summer ’23. You can opt out of the automatic deployment of enhanced domains in Spring ’23 through an org-level setting. Until this feature is enforced in Winter ’24, you can disable enhanced domains. For more information, see Enhanced Domains Timeline in Salesforce Help.”

If you would rather just fix the issue, Salesforce have documented a useful guide of common issues and how to resolve them too!

This is fantastic, everything is fine!

Well done, but don’t rest too lightly — remember your test results are only as good as your coverage! If you’re happy with your results we still recommend that you ensure you have post enablement reporting set up to check for anomalies, especially on system integration after the auto-enablement. Not everything that can fail will be visible, especially 3rd party AppExchange apps who’s debug log entries won’t be visible to you.
