Hi Martin, first of all thanks for taking some time to read and provide feedback, much appreciated.
I firstly tried with CentOS 7.x (build 1511) but got the same errore during CA configuration. Then I supposed I had to upgrade step-by-step, from 3.0 to 3.3 (instead of 3.0 to 4.x) and used Fedora 23, 20, 19 and 18 but with no luck. If you need the exact log from CentOS 7.x migration I can provide them to you. About the debug log file, it was attached and these are the final lines containing the error: [09/Feb/2016:15:31:42][http-bio-8443-exec-3]: getDomainXML: domainInfo=<?xml version="1.0" encoding="UTF-8" standalone="no"?><DomainInfo><Name>IPA</Name><CAList><CA><Host>ipaserver.it.fx.lan</Host><SecurePort>443</SecurePort><SecureAgentPort>443</SecureAgentPort><SecureAdminPort>443</SecureAdminPort><SecureEEClientAuthPort>443</SecureEEClientAuthPort><UnSecurePort>80</UnSecurePort><Clone>FALSE</Clone><SubsystemName>pki-cad</SubsystemName><DomainManager>TRUE</DomainManager></CA><CA><Host>ipaserver-ha.it.fx.lan</Host><SecurePort>443</SecurePort><SecureAgentPort>443</SecureAgentPort><SecureAdminPort>443</SecureAdminPort><UnSecurePort>80</UnSecurePort><SecureEEClientAuthPort>443</SecureEEClientAuthPort><DomainManager>TRUE</DomainManager><Clone>TRUE</Clone><SubsystemName>pki-cad</SubsystemName></CA><SubsystemCount>2</SubsystemCount></CAList><OCSPList><SubsystemCount>0</SubsystemCount></OCSPList><KRAList><SubsystemCount>0</SubsystemCount></KRAList><RAList><SubsystemCount>0</SubsystemCount></RAList><TKSList><SubsystemCount>0</SubsystemCount></TKSList><TPSList><SubsystemCount>0</SubsystemCount></TPSList></DomainInfo> [09/Feb/2016:15:31:42][http-bio-8443-exec-3]: Cloning a domain master [09/Feb/2016:15:31:42][http-bio-8443-exec-3]: WizardPanelBase updateDomainXML start hostname=ipaserver.it.fx.lan port=443 [09/Feb/2016:15:31:42][http-bio-8443-exec-3]: updateSecurityDomain: failed to update security domain using admin port 443: org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 50; White spaces are required between publicId and systemId.
