Technology has always been a bridge, but today, it feels more like a mirror. With the rapid rise of AI , we are seeing things enter our lives and leave them at a pace we can barely track. To understand where this is going, we first have to understand how technology actually impacts the core of who we are. The Survivalist vs. The Ego Our minds are biologically wired for one thing: survival . We are designed to handle the worst-case scenario, an ancient instinct gifted to us by nature. We consider ourselves conscious decision-makers, but a critical question remains: Who is really making the call?
Are you thinking about finally making the jump from Salesforce Classic to Lightning Web Components (LWC)?
Honestly, that’s a smart move. While Classic served us well for years, LWC offers the kind of speed, flexibility, and modern interface that today's users actually expect. But let’s be real for a second—migrating isn't just about flipping a switch. It’s a project that needs a plan.
If you jump in without looking, things can get messy fast. To help you avoid the headaches, I’ve broken down the key activities and essential tools you need to check off your list to nail this migration.
1. Look Under the Hood (Evaluate Your Org)
Before you start writing code or moving pixels, you need to understand the beast you're dealing with. Salesforce Classic orgs can accumulate a lot of "clutter" over the years.
Take some time to:
Review your data model. Is it clean, or is it a web of redundant objects?
Audit custom objects and fields.
Analyze your technical debt. Look closely at your existing Apex code and legacy Visualforce pages.
This step is arguably the most important. You can't build a solid house on a shaky foundation.
2. Build Your Migration Strategy
Now that you know the state of your data, don't just wing it. You need a game plan.
Prioritize Features: You don't have to move everything at once. Which features does your business rely on daily? Move those first.
Plan the Data Move: How are you getting your records from A to B? Make sure you check out Salesforce's native tools for data migration.
Map out Testing: How will you know it works? Define what "success" looks like before you start building.
3. Get Comfortable with LWC Development
If you’ve been working solely in Classic or even Visualforce, LWC is going to feel different. It uses modern web standards, which is great for performance but might require a skills refresh.
Invest time in learning the framework. Salesforce offers some fantastic Trailhead modules and documentation. Trust me, spending a week learning the best practices now will save you months of bug-fixing later.
4. Rebuild Those Visualforce Pages
This is usually the heavy lifting. Most Classic orgs are heavy on Visualforce pages. Since these won't look or feel right in the Lightning Experience, you’ll need to rebuild them using LWC or Aura components.
Look at this as an opportunity, not a chore. It’s your chance to redesign the user experience (UX) and make those pages faster and more intuitive than they ever were in Classic.
5. Update Your Apex Code
LWC and Visualforce talk to the server differently. While your backend logic might remain similar, you will likely need to tweak your Apex code.
Review your classes to ensure they are efficient and secure. LWC relies heavily on @AuraEnabled methods, so you'll need to update your controllers to handle data passing correctly.
6. Use the Right Tools for the Job
You don't have to do this manually. Salesforce actually wants you to migrate, so they’ve provided a suite of tools to help you out:
Salesforce Optimizer: This scans your org and gives you a report on how to clean up and optimize your setup.
Lightning Experience Readiness Check: Run this early! It assesses if your org is ready for the switch and flags potential blockers.
Lightning Experience Transition Assistant: This is basically a wizard that guides you through the process step-by-step.
7. Test, Test, and Test Again
I can't stress this enough: Testing is not optional.
You need to perform unit testing, integration testing, and most importantly, User Acceptance Testing (UAT). Just because the code compiles doesn't mean it works for the end-user. Make sure the LWC-based application handles real-world scenarios before you deploy.
8. Train Your Users
Imagine walking into your office and someone has rearranged all the furniture. That’s how your users will feel if you switch to Lightning without warning.
Prepare them for the transition. Run training sessions, create cheat sheets, or share short videos. If they know how to navigate the new interface, adoption rates will skyrocket.
9. Monitor and Optimize
Going live isn't the finish line. Once you’ve migrated, keep an eye on things.
Monitor the performance of your Lightning Web Components and listen to user feedback. Are pages loading fast? Are users clicking fewer times to get the job done? Use this data to tweak and improve the system continuously.
10. Don't Be Afraid to Ask for Help
If you look at your org and feel overwhelmed—maybe the logic is too complex or the data volume is massive—it’s okay to call in the cavalry.
Consider hiring a Salesforce consultant or a developer who specializes in LWC migration. Sometimes, an expert eye can spot pitfalls you might miss.
Final Thoughts
Migrating from Salesforce Classic to Lightning Web Components is a big project, but the payoff is huge. You get better performance, a mobile-ready interface, and a happier team.
By following these steps and using the tools Salesforce provides, you can ensure your transition is a success. Good luck with the move—you’ve got this!
