I am using port 8010 now and we want to change this to be https and port 80 - can I do this without reinstalling?
https will use port 443 and will need a certificate installed. Is this what you want? To just change the port in SSA you can open the server.xml in the folder Tomcat7\AnalystConnect\conf and search for the line starting with <connector. This line will have a port attribute. You can change this to port 80 for http. You can also add a line for port 443. Please read this documentation for installing a certificate into Tomcat: https://tomcat.apache.org/tomcat-7.0-doc/ssl-howto.html
The typical way I do this is using an IIS on Windows to handle the SSL access and forward request to SSA. In this case you will be able to run all SSA services on one port including SSL. Follow this documentation to install an ISAPI filter in IIS: https://tomcat.apache.org/connectors-doc/webserver_howto/iis.html
Finally you need to change the URL's in the shared.properties file in customerconfigurations\_global_ to match the new port and protocol. You need to do this in any case you change the port and/or protocoll to use for SSA.
Unfortunatley we don't have a documentation for this
