The CS_REQ_MIGRATE request capability indicates if a client supports the migration protocol and if the client is capable of migrating to another server when requested. You can use srv_capability_info() to retrieve the CS_REQ_MIGRATE capability information. For example:
CS_RETCODE ret; CS_BOOL migratable; ret = srv_capability_info(sp, CS_GET, CS_CAP_REQUEST, CS_REQ_MIGRATE, &migratable);
