Some freeware can be better than many commercial alternatives, and other freeware is absolute unmitigated crap that isn't even worth free. Linux is a prime example of how good free software can be.
Best thing you can probably do, is set up a small test area. Maybe a few systems that you could afford to be down for a day or two if necessary. Try the program out, see how it works for what you need. If it seems to work well, you can gradually add more and more systems to your testing sample until either you find it won't work for your needs or you feel confident that it will and can migrate every system.
OK so I'm a fan of freeware but not for work, so call me biased!
Anyway in one of my many boring sat. lunchtimes, I came across a link on another forum to a freeware enterprise backup system called Indigo Backup. It has had pretty good reviews but that means little in my experience!
Haven't tried it properly myself yet as the need hasn't arisen at work yet - but it will! Anyone tried it? If not maybe someone with a test network might want to try it and let me know if it's any good???!!! Not that I'm worried about screwing up the work network or anything!
All views appreciated!
