You should adaptive-enable the services to be managed by ACC. For this, services should be implemented in a virtualized manner. This means that the application service is decoupled from the underlying computing node with its file systems and settings. This allows the services to move across the computing nodes in the AC landscape. There are also traditionally installed systems which cannot move across computing nodes.
...
1. Setup all the application service relevant data on a central storage system.
2. Manage OS-related settings like users, groups, services, and hostnames using a central management tool like Network Information System (NIS) or LDAP (in case of Microsoft Windows, it is Microsoft Active Directory).
3. Install the application services on virtual hostnames to ensure that it is always reachable by the same hostname and IP address, irrespective of the resource on which it is running. To host the application services, the computing node must be assigned with its own physical IP address and the virtual IP address of application service.

4. To use the managed application services, you need to adjust the profiles. You need to ensure the following settings in the instance profile:
SAPLOCALHOST = <virtual hostname>
SAPLOCALHOSTFULL = <full qual. virt. hostname>
icm/host_name_full = <full qual. virt. hostname>
