RT 4.2.7 Multi-instances

Hello

I went through the information on the wiki pages
http://requesttracker.wikia.com/wiki/MultipleInstances&cd=1&ved=0CBsQFjAA&usg=AFQjCNHsXyZLstK8-4Jt-2H3LrPY1PNUBA&sig2=S8azqL1IpYsijyaSQEwvwA

Is there something more recent on this subject? Does it apply to 4.2.7?

Thanks
