ACS 5.8 to ISE 3.0 migration: The server selected protocol version TLS10 is not accepted by client preferences [TLS12]
Tried to migrate ACS 5.8 to ISE 3.0 but I was getting following message: “The server selected protocol version TLS10 is not accepted by client preferences [TLS12]”.
Since TLS 1.0 is disabled by default I had to enable it in java control panel (Oracle java 1.8) and also edit file C:\Program Files (x86)\Java\jre1.8.<some_version>\lib\security\java.security, remove TLSv1 from option jdk.tls.disabledAlgorithms and finally restart the migration application.
You can do the same in linux environment for openjdk by editing /usr/lib/jvm/java-11-openjdk-amd64/conf/security/java.security
Tnx to stackoverflow
