Both the company that we acquired and us are using AAM, Target and Adobe Analytics, but we had different org ids in the past. What are the different ways to combine/sync our Marketing Cloud IDs and allow use cases like sharing our AAM segments including online and offline customer data with their Adobe Target for personalization? Thank you!
You can get in touch with your Account Manager and ask to enable Audience Market place for both AAM accounts. If it is already enabled you should be able to see Audience Marketplace in AAM UI. Using Marketplace, one partner can create data feeds and other can subscribe for that data. Check private data feeds article : Audience Marketplace
Other option would be to check with your account Maanger and ask them to configure second party data share between both partners, both parties will have to contact AAM consulting or their Account Managers. This would require creation of data sources and destinations on both AAM accounts.
i would recommend interacting with your account manager for this particular query. Since, this requires custom provisioning in your accounts and the acquired company. The products and services cannot share segments and others assets across Org Ids unless provisioned from Adobe.
We would recommend to interact with account managers or consultants for the same.
