1 TB is a fairly large size.You can us the Aperture Import Plugin.See https://helpx.adobe.com/lightroom/help/import-iphoto.html
Now the Time to import depends on your computer(RAM,Processor,Disk read/write speed etc)
You should select "External Drive" to be the Destination where you will copy your 1 TB Files.Click "Select" next to "Copy images/Videos" to and select location.
Should I split it up and do it piece by piece or all at once
Import Plugin from Aperture does't offer you to split the Aperture Library.This requires a different Approach.You need to do this manually
- Navigate to your Pictures Folder
- Right click on Aperture Library
- Select "Show package Contents"
- Copy Masters Folder to External Drive.
- This folder Contains all the Pictures you have in Aperture.You can import them to Lightroom from File>>Import Photos and Vidoes
- And you can have Different catalogs
Thanks for the response. I tried the plug-in and it sat in limbo for a few hours with no response and nothing imported and I did a "force quit".
I am using an external 4TB drive connected to an iMac. I was unable to even get to the point to choose the external drive.
What is your Computer Configuration?
Also try the second way I mentioned.
You can select as many folders you want from the Masters folder.This way you can split the Aperture Library into different or one Lightroom catalog
The Masters folder is already on the external drive.
I am running an iMac 3.4 GHz Intel Core i7, 16 GB 1333 MHz DDR3, with a LaCie 4TB external drive for my photos
Simply follow the process I mentioned and let us know if that helps
Working on it now...says about 4 hours to copy approx 120,000 files :-)
It looks like this will work already...I just checked while it was still in process of copying the files and I will be able to split it up.
When I get it all imported into the lightroom folder can I delete the old Aperture Library to free up an extra 1TB of space?
So I will delete the Aperture Library but keep the Masters folder...
Can I move the Masters folder into the Lightroom Catalog Folder?
Haven't done anything yet...still over 3 hours to copy.
Yes You can do that.Simply select Add while importing provided your computer have good space on Primary disk(Mac Hd)
*Remember Selecting Add means you need to leave your Hard drive connected to computer in order to work on your Pictures
