How to Update Legacy Modules in Make.com

This how-to guide explains step by step how to update legacy modules to new modules in make.com so you can modernize your scenarios without breaking existing automations.

Legacy modules remain functional, but they do not receive new features. Updating them to new modules in make.com ensures better performance, improved reliability, and long-term support for your workflows.

Before You Update Modules in Make.com

Before changing any scenario, understand what will happen when you replace a legacy module with a new module in make.com:

Legacy modules continue to run, but may be deprecated later.
New modules generally offer more configuration options and better API coverage.
Input and output structure may differ between legacy and new modules.
You might need to adjust mappings and filters after replacement.

Always review your scenario behavior carefully after you switch modules in make.com to make sure results remain correct.

Identify Legacy Modules in Make.com Scenarios

To start, you must find out which modules in your scenario are considered legacy:

Open your scenario in the Make editor.
Look at each module name and icon in the canvas.
Legacy modules usually have Legacy in their name or are marked differently in the app listing.
Compare them with the current apps list to see if a newer equivalent exists.

Once you know which modules are legacy, you can plan how to update them to the new modules in make.com.

General Strategy to Replace Legacy Modules in Make.com

Use the following high-level strategy whenever you replace a legacy module with a new module in make.com:

Work module by module, not the entire scenario at once.
Keep the legacy module in place until the new module is fully tested.
Map fields in the new module to match your previous outputs.
Test after each replacement before moving to the next one.

This approach reduces the risk of breaking production workflows in make.com.

Step-by-Step: Updating a Legacy Module in Make.com

Follow these steps to replace a single legacy module with a new module in make.com:

1. Analyze the Existing Legacy Module

First, document how the legacy module works:

Note its type (trigger, search, action, aggregator, etc.).
Review its configuration fields and values.
List all outputs it provides to later modules.
Check filters and router branches that depend on this module.

Take screenshots or export the scenario so you have a reference when building the new module setup in make.com.

2. Locate the Equivalent New Module in Make.com

Next, find the new module that replaces the legacy one:

Open the apps list in the scenario editor.
Search for the same app (for example, the same SaaS or service name).
Review available modules under that app in make.com.
Identify the module that covers the same function as your legacy module (for example, Create Record vs. Add Item).

Sometimes, one legacy module maps to several new modules or vice versa. Make sure you understand the required logic before you build.

3. Add the New Module Next to the Legacy Module

Do not remove the legacy module yet. Instead:

Place the new module immediately after the legacy module, or in a test branch.
Configure connection and authentication for the new module in make.com.
Map inputs using the same data the legacy module received.

At this stage, the legacy module continues to run, and the new module runs in parallel for testing.

4. Match Input and Output Fields Carefully

New modules often expose more granular fields or slightly different names. To preserve scenario behavior in make.com:

Compare each input field in the legacy module with the equivalent field in the new module.
Adjust mappings where field names or structures changed.
Use functions (for example, map() or get()) when the new module expects arrays or objects.
Check date formats, IDs, and custom fields carefully.

Then, review all modules that use data coming from this part of the flow and confirm they still receive the needed items.

5. Update Filters, Routers, and Dependent Modules

After field mapping, update the rest of the scenario that depends on this data:

Open each filter that references the legacy module output.
Change the source of each condition to the new module output instead.
Review routers and branches that used old fields.
Update any aggregators or iterators that rely on old array structures.

This ensures your scenario logic in make.com stays consistent after you switch modules.

6. Test the New Module in Make.com

Now test the scenario thoroughly:

Run the scenario in Debug mode.
Send representative test data through the flow.
Check execution details for both legacy and new modules.
Confirm that records are created, updated, or retrieved as expected.
Verify no errors occur in downstream modules.

Repeat the tests with several variations of data so you are confident in the new configuration.

7. Deactivate and Remove the Legacy Module

When you are satisfied that the new module works correctly in make.com:

Redirect all downstream mappings and filters to use only the new module outputs.
Disable or remove the legacy module from the scenario.
Run one more full test with the legacy module removed.
Save and, if needed, turn the scenario back on for production.

At this point, you have a clean setup using only the new modules in make.com.

Tips for Safely Migrating Multiple Legacy Modules in Make.com

If your scenario contains several legacy modules, follow these best practices:

Replace modules one by one, not all at the same time.
After each replacement, run focused tests on that part of the flow.
Use scenario versions so you can revert if needed.
Schedule migrations for low-traffic hours.

For complex business-critical scenarios in make.com, consider planning the migration in a cloned scenario first, then switching production traffic after validation.

Advanced Considerations for Make.com Migrations

Beyond the basic replacement steps, keep these advanced points in mind:

Rate limits and quotas: New modules might handle pagination and limits differently.
Error handling: Check how the new module reports errors and adjust error handling routes.
Data structure changes: New modules may return nested objects; update JSON parsing or transformation steps accordingly.
Security: Confirm that connections in make.com use the most secure authentication method available for the app.

Monitoring scenario executions for a few days after the change helps you catch edge cases early.
