Allow create and validate profile WITHOUT actually syncing and creating objects
I went to use the validate powershell scripts, but they couldn't be run without having a profile. I couldn't create a profile without actually importing and synchronizing the CSV files that are being imported. There should be a way to create the profiles and test against them, even viewing your data in Your Organization view, while not actually making you import and sync right away which creates the groups, users (if configured), and associations. This is just a very trimmed down feature set which needs to be expanded to provide enterprise level options and support.

I had the same issue. School Data Sync Toolkit documentation needs to be updated. The current documentation says you need a profile name to run pre-sync validation. You cannot have a profile without uploading an initial series of CSV files. I suppose I could create blank files to create the profile, but if that is necessary your documentation should reflect this. I'm afraid I'll break something if I upload blank files during profile creation.
