Migration on AWS

Hello 

We'll move one of our customers F5 cluster to another cluster due to the license type changes. The former cluster which will be replaced have BYOL license and new cluster will use utility (aka PAYG). We have already deployed a new pair of devices and migrate the configuration from older to new cluster using UCS files. Now we only need to reassign EIP and secondary IP addresses to the new cluster to be able to move everything. And this step is the job for another day. Both clusters coexists in same networks and they have same amount of resources. The newest cluster is currently shutdown becouse, if they do failover they manipulates the EIPs on the former cluster and this causes the traffic disruptions. Since new cluster can manipulate the IP mappings on old cluster through AWS, i should had a new CFE definition along with the key elements IAM, S3bucket and tags for this new cluster. I guest that i misscalculate this step.

My first question is: Can somebody guide me about this? 

While restoring the config we used UCS files and thus CFE config came along with the original config. Hence, we lost original CFE declerations came with the initial configurations when we deployed from cloudformations. But i have UCS files that created right before the the migration. Probably you know that cloudformations dynamically creates these cfe declerations, tags, s3buckets, and iam definitions during deployment.

The second question is: Does somebody know where f5 store cfe configurations? Since the CFE config can be applied with the ucs files there must be some sort of configuration file that hold the cfe declerations.
