Can Robocopy still work for long path name?

Question

I'm about to migrate file server from Windows Server 2008 SP2 to Windows Server 2019 by using Robocopy. Before I do robocopy I'm trying to export out the permission using Get-ChildItem and script from https://social.technet.microsoft.com/wiki/contents/articles/51422.how-to-export-folder-permissions-to-excel-or-csv-file.aspx

However, during the export process I received error saying that the path are too long and it couldn't export out the permission. This issue I've created another question in Microsoft Q&A forum.

So for this one, can anyone kindly advise if I can still do the robocopy if the folder path names are too long? Because I'm going to ignore this and proceed with the Robocopy, just to avoid any issue came out during the copy process.

Hi,

By default, ROBOCOPY will accept UNC pathnames including UNC pathnames over 256 characters long and it also provides a flag that lets you turn OFF support for long path names (flag: /256)

"/256 Turns off support for paths longer than 256 characters."
