Load Config from one Single IP F5 to another Single IP F5

Hi All,

We use a ELB -> Active/Active F5 cluster in AWS, which we do without using the cloud scripts provided by F5 ( multiple reasons why ). My upgrade path in the past is to create two new EC2 F5 instances ( via a new AMI that matches the version of current code on the clsuter ), cluster them to the existng solution ( so we end up with 4 in the cluster ) and then upgrade the code on the new devices and remove them from the cluster ( so we then have 2 x Active/Active clusters of 2 F5s in each cluster ). These devices run LTM/ASM.

 

I am looking at ways off de-risking the upgrade, by skipping the clustering step if possible. As the devices are all Single IP devices I would like to:

  • Still build 2 x New EC2 F5s
  • Create a UCS from the old single IP F5s
  • Load the UCS onto the new single IP F5s
  • Cluster the new F5s as required

 

So the intent of this question is basically: can I load the UCS to a new single IP F5 from another single IP F5.

  • Tried "load sys ucs UCS_12th_June_2020.ucs no-license platform-migrate" and got the below errors. ( I masked IPs )

    As you can see, as a single IP F5 the SelfIP and management IP are the same.
