Migration between F5 LTMs

We need to do apps migrations between two F5 LTM. What type of considerations do we need to take before proceeding to migration. And can we use same Virtual IP address on the new F5 load balancer? ...

Hello san. Are you just moving pieces of the config or the entire config?

 

If you are moving the entire config... Are you keeping the first device live while you do this? If so, then your best option would be to create a ucs and download it you a local machine. Upload that ucs to the new BigIP device and restore it through tmsh:

You have more options doing this through tmsh so I advise doing it that way so you can specify no license and no platform check if the devices arent the same platform.

 

When you do this just make sure it doesnt have access to the rest of your network and you should be fine. Its important to make sure these devices are not able to communicate to each other because you will probably run in to ip address conflicts which will mostly likely cause traffic issues. Once the new device is ready to be live you can switch it with the old device. As always, a maintenance window is highly recommended.

 

If you are just moving parts of the config then you can just create the config objects on the new device and remove them from the old device. You do not want to use the same self ips because you will come across ip conflicts.

 

Hope this helps.
