Hi FYates,
If you use the same catalog file on your new system as well, then everything will be same like your edits, collections, keywords, rating etc.
Default Location for Lightroom Catalog
Windows
C:\Users\[user name]\Pictures\Lightroom\Lightroom 6 Catalog.lrcat
Mac
/Users/[user name]/Pictures/Lightroom/Lightroom 6 Catalog.lrcat
Refer: Preference file and other file locations | Lightroom 5
You also need to copy the Images as well in the same file structure on the new system.

Hope it helps.
