Migrating an NSX Data Center for vSphere environment and its existing integration with vRealize Automation to a new NSX-T Data Center environment requires planning and preparation.
You must deploy a new NSX-T Data Center environment for this migration. You cannot merge vRealize Automation deployments from your NSX-v environment into an existing NSX-T Data Center environment, which is preconfigured and used.
In addition to setting up a new NSX-T Data Center environment in advance, migration preparation might also require you to modify your existing NSX-v environment.
You should be familiar with NSX-T concepts, vRealize Automation concepts, and administration tasks in both environments before you migrate.
