= Preparing an Instance HA deployment for adoption

[role="_abstract"]
To enable the high availability for Compute instances (Instance HA) service after you adopt the {rhos_long_noacro} ({rhos_acro}) {rhos_curr_ver} data plane, perform the following preparation tasks:

* Create a fencing configuration file to use after you adopt the {rhos_acro} data plane.
* Prevent Pacemaker from monitoring or recovering the Compute nodes.
