NetWeaver 642 and R/3 4.6C in the same Operating System?

Hi people,

I have a R/3 4.6c (Oracle) testing system in Windows XP and I was wandering if it is possible to install in the same OS the NetWeaver EP 6.0 SP9 (MaxDB) release.

It is possible to have both of them?

Are there any known possibilities to damage the 4.6c?

Someone has done this before?

Thank you for all answers.

Adrian
