Hi, now Apple will stop supporting Aperture I intend to switch over to CC and Lightroom. If someone can point me at the best resources I will be very happy, but meanwhile I have the following specific questions. I will be very grateful for your replies, and both your general and specific advice.
THis should answer most of your questions
As far as I know, once you are done with the conversion, you can still edit the photos in Aperture if you want.
Thanks for this link, it looks very helpful indeed.
