Also curious if anyone has found the reason for the "Failed to load data from Extensions table of project". I've been able to move/upgrade 8 projects from QC 10 to ALM 11.52 on new infrastructure with no problems. I've followed the same procedure for each but now for some reason the 9th project is giving me this error when I try and restore it to the ALM 11.52.
Any help is greatly appreciated.
