Salesforce Summer ’25 Release: Dates, Sandbox Prep & What You Must Know
As we step into the warmer months of 2025, the Salesforce community is gearing up for one of the most anticipated events of the year — the Salesforce Summer ’25 Release. Packed with performance enhancements, platform updates, and fresh features, this release marks another critical milestone for orgs looking to stay ahead with scalable and intelligent CRM solutions.
But before the new capabilities go live, there are a few crucial preparations every Salesforce admin and team should make. Let’s break it down — from release timelines to sandbox readiness, and what steps you should take to ensure a smooth transition.
When Will Your Salesforce Org Be Upgraded? 🔄
Salesforce doesn’t roll out updates all at once. Instead, upgrades happen in waves across different weekends — depending on your specific instance. For Summer ’25, here are the four primary release windows:
May 10, 2025
May 17, 2025
June 7, 2025
June 14, 2025
To find the exact upgrade schedule for your org, head over to Salesforce Trust, enter your instance name or domain, and click on the Maintenance tab. This will reveal the precise date your production environment will switch to Summer ’25 — allowing you to plan ahead, especially for testing mission-critical processes.
Pro tip: If you’re unsure of your instance, navigate to Setup > Company Information in Salesforce. Your instance name is listed there.
Sandbox Preview: Why It’s a Must-Do 🧪
Before your production org gets upgraded, your sandbox environments will be your best friends.
Salesforce divides sandboxes into Preview and Non-Preview types. Most sandboxes will receive the Summer ’25 update starting May 10, 2025 — though exact timing depends on the instance type. Getting your sandbox into a preview window lets you test custom features, integrations, flows, and Apex code in a controlled setting.
This is where you identify potential compatibility issues or performance hiccups — without impacting live data or users.
Reminder: Don’t rely solely on pre-release orgs. While useful for exploring new features, they don’t reflect your configurations or customizations.
Pre-Release Orgs: A Sneak Peek Into the Future 🚀
Pre-release orgs are Salesforce’s way of offering a test-drive of upcoming features. These environments are usually made available a few weeks before sandbox upgrades and are perfect for early feature exploration, UI reviews, and experimenting with the latest tools.
However, keep in mind: pre-release orgs are clean slates — they don’t contain your org’s metadata or data, which limits how deeply you can validate real use cases.
Still, for admins and product managers, these orgs are a fantastic way to get ahead of the curve and start prepping enablement materials for teams.
Your Summer ’25 Preparation Checklist ✅
Here’s a quick rundown to help you get ahead of the Summer ’25 upgrade:
Identify your instance upgrade date via Salesforce Trust
Confirm sandbox preview availability and schedule testing
Spin up a pre-release org for early feature exploration
Read the release notes thoroughly once available
Test custom features and integrations in sandbox
Update training materials and documentation
Communicate changes to internal stakeholders and end users
Final Thoughts
