It is not difficult.
It is a migration, as is documented.
I am working on a KA about upgrading to 12.0.
In your case, you:
Stand up a new 3-node 12.0 cluster.
Do a backup of your old cluster.
Restore to the new cluster.
There are some other details to be aware of in the upcoming KA.

No more in-place upgrades then? That's unfortunate.

In-place upgrades from 11.3 on CentOS 7 to 12.0 on CentOS 7 are supported. Similarly there will be an in-place from 12.0 to the next version after that.
The thing is that there is no in-place upgrade for the operating system from CentOS 6 to CentOS 7. Unfortunately, that is out of our hands. That is why we recommended that during the lifetime of 11.3, customers should migrate from CentOS 6 to 7.
