Hi Peter,
We’ve been working on 6.1.2 for a few months now, but we didn’t do a regular migration, but instead have slowly been building new in it. So far, I think it’s a great improvement over 5.8, but I suppose I haven’t gotten too far into the weeds yet. The GUI does take a bit to get used to, but it’s growing on me. I love the SMAT DB and the Database tools so far.
We are on RHEL 7.1 OS VMs.
