Hello,

Is there a method to translate an existing bigip ltm configuration (bigip i2800 version 15.1.5.1) to a more recent version (rSeries 2600 Bases OS version 1.5.0 Service version 1.5.0..).

How is it possible to export and import configuration or pieces of configuration like hosts?

Can you explain me how to do this please ? With some examples of commands if you know.

Regards

Eric

F5OS is a hypervisor than runs on rSeries appliances.

“BIG-IP TMOS” is the tenant you run inside the hypervisor on rSeries, or on bare metal on iSeries or older platforms, or as a VM on vSphere or KVM, etc.

So to migrate your config from your existing 15.x on iSeries to 15.x on rSeries, you’d typically:

1- Make a UCS backup

2- Deploy a 15.x tenant to F5OS

3- Restore the UCS to the new tenant

As Lucas described, the F5OS is just the hosting hypervisor.&nbsp; The guest can run the same (or newer) version BIG-IP TMOS as the existing.
