Approaching: DTM Sunset Milestone 2




March 2020 Update: Due to the situation with SARS-CoV-2 and COVID-19, we have pushed out the dates for Milestone 2 and 3 by 3 months each.  The dates below have been updated to reflect these new dates.  We will continue to monitor the situation and may make further adjustments depending on how the next few months go.


July 2020 Update: We continue to hear from customers who are concerned about the impact that the COVID-19 pandemic is having on their migration timelines. We have resource, maintenance, and cost constraints that make it infeasible to push back Milestone 3 (the final EOL), but we have decided to shrink the read-only period from 6 months down to 2 months. This means that while the final EOL timeline is not changing — it is still April of 2021 — you’ll be able to continue to make changes to your DTM properties until February of 2021. The official dates below reflect the latest changes.


It’s been about 2 years since we made Adobe Experience Platform Launch generally available to all Experience Cloud customers.

Six months after that we announced that DTM would be entering a maintenance phase where security updates would be made, but that no new feature work would be happening. At that same time, we announced that DTM would eventually reach a sunset and provided a timeline for increasing restrictions on DTM functionality over the course of time.

This was done so that development efforts could focus on Launch which is now the recommended way to deploy any Adobe Experience Cloud solution and to stream your site and application data into the Adobe Experience Platform.

Last July, we passed Milestone 1 of the DTM Sunset Timeline and we removed the ability to add new properties in DTM.

On February 16, 2021, we will hit DTM Sunset Milestone 2. Starting on that date, DTM properties will enter a read-only state. This means:

  • You will still be able to login to DTM, but your properties, rules, data elements, and tools will all be view only.
  • You will be able to see everything that is there, but you will not be able to make any changes to any of the resources.
  • You will not be able to publish any new libraries.

Any libraries that have been built will remain in place, so sites that are referencing a DTM library will continue to retrieve and execute that library, but you will no longer have the ability to modify the library contents in any way.

DTM properties will remain in this read-only state until April of 2021 when we plan to decommission the product and DTM will no longer be available.

dtm migration launch



If the Launch migration tool is run on DTM, will it allow for modifying the rules/data elements in Launch?




@MMMMC, yes, when you run the migration tool, it creates a matching property in Launch, but does not publish anything.  You are free to make any modifications and test (heavily encouraged) before you publish anything.  Depending on whether you link your DTM embed code to Launch, the Launch library will actually start being served to browsers when (1) you publish to Production in Launch or (2) when you replace your DTM embed code with a Launch embed code.  There's a high-level outline here and FAQ in the product docs with more info.




As adobe have extended the sunset dates for DTM. Could you please confirm the API's as well are they extending the dates  ?
