unistall DataServices

Hi,

I'd like to unistall DS aplication from server.

But on the same server is BusinessObjects BI platform.

Should I do something befor this operation or just unistal -> next - > next?

I'd like to avoid remove some files which are shared with BOE

DS version: 4.2 SP3

BOE version: 4.1 SP5 FP2

Aplication server: Windows 2008 R2

Regards
