Updating glibc on a SuSE OpenExchange box

Does anyone here have familiarity with the SuSE OpenExchange Server OS?

I am wanting to update glibc-2.2.5-179 to glibc-2.3.2-6.i586.rpm so that I use a packages called metamail-2.7.19-783.i586.rpm, which also needs sharutils-4.2c-492.i586.rpm installed.

Basically am I asking for trouble updating the glibc from 2.25-179 to 2.3.3-6?

Thanks for any information,

Christian
