If a domain is already registered within HEXONET you will have to request a so-called usertransfer

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<epp xmlns="urn:ietf:params:xml:ns:epp-1.0">
  <command>
    <transfer op="request">
      <domain:transfer xmlns:domain="urn:ietf:params:xml:ns:domain-1.0">
        <domain:name>testdomain123.com</domain:name>
        <domain:period unit="y">1</domain:period>
        <domain:authInfo>
          <domain:pw>xxxxxxxx</domain:pw>
        </domain:authInfo>
      </domain:transfer>
    </transfer>
    <extension>
    <keyvalue:extension xmlns:keyvalue='http://schema.ispapi.net/epp/xml/keyvalue-1.0'>
      <keyvalue:kv key='ACTION' value='USERTRANSFER' />
    </keyvalue:extension>

    <clTRID>ABC-12345</clTRID>
  </command>
