Mostly.  I don't think anything changed between the two versions for me.
I may have had to make a couple of changes but nothing bad.

I'm using the latest tarball without problems.  Some things have changed
(check_ping now reports duplicate packets, check_ssh now requires you to
put your arguments in a certian order) but nothing major.

I installed on a new box, but I think the best bet is to install in a
new directory and change your apache links to goto the new one.  That
way you can back out if something goes wrong. 

I noticed that 1.2 used more memory and CPU than 1.0b4.  The memory may
have just been because of different options, but it definately seemed to
be hitting the CPU harder.  I upgraded to 2.0 and the load dropped from
12 to 0.5.  The memory dropped from 1.2Gb down to about 600Mb.  

People have suggested the chained hash patch to fix the performance
problems and I definately think its a good idea if you're not ready for
nagios 2.0.

Agreed, 
Thanks for the excellent program.
