Do Leopard and Tiger like each other?

[Ashley Aitken]

Howdy All,

It's Leopard time (at last).

I'm considering how best to upgrade to Leopard on a number of  
machines. It seems (as a result of some information from Apple and  
others) that various things in Leopard are "incompatible" with Tiger  
(e.g. Address Book, iCal) and Leopard may automatically update data  
when installed.

Most of my machines have user data on a separate partition to the OS  
and another partition.  I am wondering whether I can install Leopard  
on the other partition and set-up the accounts to use the user data,  
and then still be able to boot from the Tiger partition if things  
don't work out.

So the question is: how well can Leopard and Tiger live together on  
the same machine, dual booting and sharing user data, at least for a  
while?  Any experiences?

Thanks in advance,
Ashley.

PS Most of these machine also sync their data with a (shared) .Mac  
account (although I don't mind turning that off for a while).
