Subject Re: Fastest way to upgrade from 7.0.10 to 7.0.11?
Date Sat, 12 Mar 2011 23:37:42 GMT
Hi Mark,

Thanks a lot for your response. I did agree with Charles regarding the
usually bad idea about just replacing JARs, but in this specific case
(7.0.10 to 7.0.11) I suspected it could be done just replacing JARs.
I will try it definitely.
