I've just now published a Logic App template for X12 connector control numbers replication for disaster recovery on Azure quick start template on GitHub.
This enables a very easy tryout with the "Deploy to Azure" button:
As well as powerful automation using either Azure CLI or Azure PowerShell to deploy the same with customized input parameters. See the Azure quick start template readme for details on deploying the samples from either.
These replication Logic Apps build upon the soon to be released X12 connector triggers and actions for control number change.
