If you are familiar with log4j.xml it is fairly easy to convert a 
log4j.xml to logback.xml. The hard part is mapping log4j classes to 
their logback equivalents. (We have a tool which automates such 
conversions for log4j.properties files).

As for your Logger extensions, Markers may give you the flexibility you 
are looking for. What does your logger extension do?
