I have a windows server with jumpbox where alfresco 3.0 is running with a mysql database. How it is possible to integrate in a mac os server with alfresco 3.1 and a mysql database all users and other files from the old system? it is a way to create a backup in 3.0 and load it in 3.1? can I before an alfresco installation change the standart port http://wiki.alfresco.com/wiki/Changing_Default_Port_Configuration because of a running mailserver?
