(Optional) For users who use HTTPS protocol to access their Nexus instance without a known certificate

If you already have a Nexus instance with an SSL certificate that is not recognized in your Java environment, you need to do migrate it.

1. Download the certificate from the Nexus server:

   openssl s_client -connect <server>:<port> -showcerts > myserver_cert

2. Install it into the Java instance used to launch the migration tool:

   keytool -importcert -trustcacerts -file myserver_cert -alias ca_alias -keystore "<JRE_HOME>\lib\security\cacerts"
