I have been tasked with ensuring that all of the contents of 3 small business servers have been migrated to a NAS device. Much of it has been moved and I need to ensure it's all moved so we can decommission the servers. I have been researching file comparison tools like WinMerge and BeyondCompare along with about a dozen others.
I do not need to go to source code level, I just need to confirm that all the files were moved. There is some duplication on two of the servers due to the existence of an Archive folder on one of them. There are thousands of files and hundreds of folders with files of various file formats.
Ultimately I also have to take the 2003-2011 folders and combine them into a Pre-2012 folder.
If someone can suggest a tool they've had success with, I'm trying to avoid doing this task manually.
