to upgrade SAP Data Services from 4.1 SP1 to 4.2 SP3

Hello,

I use SAP Data Services 4.1 SP1.

The maintenance of this tool will finish until 12/31/2014.

My solution is to upgrade SAP Data Services from 4.1 SP1 to 4.2 SP3.

My questions:

Is it to upgrade easy ?

SAP Data Services 4.2 SP3 is it a stable version ?

What are the recommendations for a successful upgrade ?

Thanks in advance.
