Migrating Windows server 2016 to the Isilon

Hi
I have been tasked with migrating our existing Windows server 2016 and all of its shares over to the Isilon. I am trying to figure out the best way to migrate/recreate our shares on this new infrastructure. I can handle the copying of the data using Robocopy and a colleague told me that NTFS permissions can't be copied via robocopy to Isilon, also he recommend me something called datadobi but my client is concerned about cost so datadobi may not be a hood candidate is what I gathered, any other suitable solution can success the migration process?

Any assistance would be greatly appreciated
