Migrating One Identity SPS HA cluster to a new appliance

Hi!

As the title says we want to migrate an SPS HA cluster to a newer Hardware with the same SPS version.
Our question: are there any documentations regarding a HW migration of a HA cluster.

We have done the migration on a single appliance following this article "Migrating One Identity Safeguard for Privileged Sessions to a new appliance (306491)" on our test environment, but we are not aware of the preferred process on how to proceed with the HA cluster.
We don't want to cause critical errors such as split-brain scenario.

Regards,
Laszlo
