CA PAM and CA PIM are two separate products, not integrating to each other in any way.
Please note, the latest version of CA PIM is r14.0.
New Features against CA PIM 12.92 are described here:
New and Changed Features - CA Privileged Identity Manager - 14.0 - CA Technologies Documentation
To my information this will be the last version of the SAM component released.
(maybe this already is argument enough for your customer to switch to the CA PAM product)
Myself working with both products I would say, from a functional point of view both products basically provide the same features.
In PIM/SAM it is possible to export the privileged accounts and endpoints via the WorldView to a CSV.
However, this file first needs to be adjusted to meet the requirements of the CA PAM product before it can be imported there.
