If it worked for K2 it would be perfect but I give it 5 stars because it's FREE.
It does wonders and I was able to shuffle content from J2.5 to J3.x in no time.
The steps to install are also really simple once you figure it out. It would be helpful if the installation procedure was explained in the download section in 3-4 lines.
Still an amazing result!
Just a stuff: I had about 800 users to recover. I had to split the users backups (100 uses at a time), because when I imported them in one time (800), I had a time out and the process was stopped. But with several splits, absolutely no problem.
Do the job as described. 5 stars for this work, guys!
