We want to do verification that all the files are there,i.e. compare the prod system to the new system we are implementing.
I've tried using an MD5 checker, which eventually bombed out because there are just so many files and folders.
I'm trying a method I wrote in powershell to check that all the files are the same and exist (note, not MD5 check or anything), we are just wanting to find out where/if we are missing gaps, but I've had it running for over 24 hours and it's only scanned 3.5 days of each year, across 8 years worth of data. so it's going to take AGGGGES.
Md5 would be nice, but it's the highest priority at this stage, but would like it to come later.
Any ideas on what I may be able to do?
