how many and which 1.6 modules are no longer available in Ps 1.7?

[ballashop]

Hi,

where can I find the specifications regarding the modules no longer used in 1.7 but that were present in 1.6?
An example:
The native Customer loyalty and rewards module is not present in version 1.7.
Another module that I didn't find is a wish list one.
These modules are active in 1.6 so if I migrate to 1.7 I will lose the data.
Are there other modules that you know are no longer active/available in 1.7 but widely used in 1.6?
I don't want to have the new site missing important data like the ones just mentioned.

Thanks for any reply.
