Rohit - I was looking for potential upgrade issues from QC version 10 to 11, and what others were saying about the process. I unfortunately have run into some performance and crashing issues.
Have you ever heard of this program called ''TestComplete''? I found an alternative to QC, when I did a Google search, I found this information at: http://breakfreefromhp.com/ - I wanted to share this. I completed a trial of TestComplete and I think I am enjoying this testing tool more.
Have you solved your upgrade issues?
Happy New Years!
