Differences in SAP Work Manager 6.3 to 6.6

[rafael_gerdin1]

Hi

I would like to know if there is major differences in SAP Work Manager 6.3 and 6.6.

What is new in terms of Agentry POJO and SYCLO?

I would also like to know what is required for such an upgrade?

We are currently using SMP 3.1.

I'm trying to figure out how much time this upgrade will require if we are going to pursue the newer version as 6.3 is already out dated.
