How to prepare for the migration from the MEP to the CEP? (for CRM teams)
Learn how to prepare your data, segments, and campaigns to ensure a seamless transition from the MEP to the CEP.
Migrating from the Mobile Engagement Platform (MEP) to the Customer Engagement Platform (CEP) is a major step forward. It allows you to manage all your engagement channels (push, in-app, email, web push) from a single dashboard, powered by a unified user profile and real-time orchestration.
While the technical migration (SDKs, APIs, connectors) is handled separately, this guide focuses on what operational teams need to do to get ready for the switch.
1. Validate your data and tagging plan
Once your user profiles are synchronized, the first step is to validate your data. From the Profile Data section, you can now check which attributes and events are available for each platform (Android, iOS, Web).
Each data point includes a source indicator by platform. Make sure that your key events (such as session starts, purchases, and subscriptions) are consistent across all platforms.
Validated data will be available for segmentation and trigger automations later.
Validate your tagging plan before creating new campaigns. This ensures that all data used for segments and automations is fully synchronized.
2. Create shared labels across all platforms
Labels in the CEP are cross-platform. This means a single label can be used from Mobile and Web pushes to Email or SMS, making campaign organization and reporting much simpler.
Navigate to the Labels tab and recreate your existing labels there. You will be able to filter, group, and report on campaigns more easily than before.
Why labels matter Labels are key to keeping your campaigns organized and measurable. They let you classify, search, and report across all campaigns, regardless of channel or platform. Well-structured labels also power cross-platform analytics and simplify capping and performance tracking. Learn more about label management in the Labels documentation.
3. Define cross-platform capping rules
Once your labels are ready, it is time to define your capping rules. Capping now works across all platforms, ensuring users won’t receive too many notifications regardless of the device they use.
You can create your new rules in the Capping tab.
If you set a capping rule of 2 messages per day, a user receiving a web push and a mobile push counts as 2, even if they’re on different platforms.
4. Create dynamic segments for recurring audiences
Segmentation has been completely redesigned in the CEP. You can now create dynamic segments that automatically update based on real-time user data. These segments can then be reused across multiple campaigns or automations.
Go to the Segments tab.
Create your audiences using the filters and attributes you validated earlier.
Save them for recurring use in campaigns.
Use dynamic segments for recurring audiences like “Active users last 7 days” or “Users with push enabled.”
5. Set your delivery speed (Send Rate)
The Send Rate (delivery speed) sets the maximum speed at which your messages are sent. It works like a speed limiter, ensuring the system never sends faster than the configured rate. The actual speed may vary depending on system load or network conditions. This helps you manage server load and control pacing during large-scale message sends.
You can adjust the send rate from the Push Settings tab when creating or editing a campaign.
6. Replicate your recurring campaigns to the CEP
Recurring campaigns created in the MEP can be easily migrated to the CEP. Use the Replicate on CEP button available in your MEP campaign list.
Once replicated, you will be able to manage these campaigns directly in the new dashboard, using the unified CEP interface.
Review the mobile landing, label, and segments once replicated; these may differ slightly depending on your new setup.
7. Recreate your trigger automations
Trigger campaigns are now orchestrated from the Omnichannel section of the dashboard.
You can recreate your previous triggers here and benefit from advanced CEP orchestration capabilities:
Multi-channel triggers
Quiet time management
Enhanced conditions
A/B/C/D testing on time, content, channel
For a full walkthrough, visit the Trigger Automations documentation.
Do not copy-paste dynamic content from the MEP to the CEP.
When migrating your push automations from the MEP to the CEP, avoid copying and pasting message content that contains personalization variables (e.g., u.optin_compositionbox_pushnotif, triggerEventAttr, etc.).
The CEP uses a different syntax and variable engine. If you copy/paste MEP content directly, your personalization rules (conditions, variables, or fallback values) will not display correctly during tests or live sends.
✅ What to do instead
Reinsert all personalization variables manually using the Insert Variable button in the CEP editor.
You don’t need to modify or remove prefixes, such as
u.because these were part of the MEP’s template language and are handled differently in the CEP.Ensure the attributes you use exist in your CEP data model. Native attributes now use the prefix
b.(for example:b.my_native_attribute).
If you are unsure whether an attribute is available in the CEP, check the Profile Data tab.
8. Prepare and activate your new In-App templates
In-App templates have been redesigned in the CEP with a more flexible format and new design options. They will be available once your mobile apps are updated with SDK 3.1.
You can already prepare these templates in advance from the In-App Templates tab.
Important
If migrating from In-App v1 to v2, you must manage this transition carefully to avoid disruption.
Here is how to:
You should activate the Switch to In-App v2 flag only when a sufficient number of users have migrated to SDK 3.1 or later.
You can estimate this share using the estimated reach feature, which filters out users running an older SDK version.
No rollback is possible: once the new endpoint is serving v2 In-App automations, you cannot revert to v1.
Existing in-app campaigns will continue to run on the MEP during the transition. Once SDK 3.1 is live, recreate your templates using the new format.
For a full overview of the new In-App features and capabilities, see the In-App documentation.
9. Review the final checklist before launching campaigns
✅ Validate your tagging plan ✅ Create shared labels ✅ Define capping rules ✅ Build dynamic segments ✅ Set your delivery speed ✅ Replicate recurring campaigns ✅ Recreate triggers in Omnichannel ✅ Prepare new In-App templates
Once these steps are complete, you are ready to launch your first campaigns on the CEP.
