I am making the leap from aperture to lightroom. I have a library of over 30k photos and I am going to start by importing them over. I went through the plug-in and was able to source my aperture library from my external hard drive and begin copying to the same harddrive (I keep all of my photos on an external drive. I am watching the import and I am getting very nervous that my current organization in aperture will be lost in lightroom (disaster!). Currently I have folders with the year labeled (ex 2015). Within those folders, I have projects for months when phots were taken (ex 12-15). then within those months I may or may not have specific events. Will this structure be maintained???? Is there a way I can import so that it is maintained??
Lightroom will import the images into the catalog.
It will keep the files in the provided location according to year, month and date format.
However, I would suggest you to export a small library from Aperture and import into Lightroom to see the hierarchy by yourself.
