Dynamics 365 Marketing Licenses Decommission - What Happens to Data? How to Backup?

One of our customers has Dynamics 365 Sales and Dynamics 365 Marketing.

They want to cancel Dynamics 365 Marketing but want to keep using Dynamics 365 Sales. If we remove the licenses for Dynamics 365 Marketing, then;

  1. What happens to the data in Marketing App? Does it stay as it is and can it be leveraged again if they decided to add back Marketing?
  2. Is there a way to backup Marketing Data?
  3. Is there anything else we should consider BEFORE removing the D365 Marketing Licenses?

Thank you in advance for your help!

Removing Dynamics 365 Marketing licenses should not impact the data in the Marketing App, but backing up the data is recommended. Options like exporting data or creating database backups are available. Consider dependencies, provide user training, and review licensing terms before removal. Consult experts for accurate information.
