Cyrus 'cluster' general upgrade strategy?

For those with medium to large scale murders or other glued together  
clusters of cyrus servers, what's the general strategy for upgrading?

Do you take downtime for the entire cluster and upgrade, or do you  
roll through upgrades of the parts?

The latter would be prudent, except that I discovered you can't  
replicate 2.3.7 to 2.3.8 (CREATE has an extra argument at 2.3.8) so  
it wouldn't surprise me if it generally isn't considered a good idea  
to mix versions like this in a murder.
