freebsd stable - Jun 2006 - Whats the difference

Hi,

I am a new member to FreeBSD on the whole. I would like to know the
differences between FreeBSD 4.7, 5.X and 6.1. My company is using BSD
4.7 currently and I would like it to change to 5 or 6. What technical
difficulties might I face or how much code would be needed to
re-written. I do understand that these are too broad questions but any
sort of input would be helpful at this stage. Please email me back to
mihir.sanghavi@gmail.com. Thanking everyone in advance.

Regards,

Mihir

Please see the article "Choosing the FreeBSD Version That Is Right For
You", at
http://www.freebsd.org/doc/en_US.ISO8859-1/articles/version-guide/index.html ,
to see if it helps your decision.

There are many improvements in FreeBSD 6 over 4, specially for new 
hardware and SMP systems (multi cpu or dual core cpus). If you have an 
old machine, which is not connected to an external network then there 
probably inst any good reason to upgrade, but i would consider it in the 
near future, as official support for 4.x has been dropped. I cant say 
what code you need to rewrite, as i don't know what application you are 
using.
