Keeping my fingers crossed that someone will answer this, I am sitting in the exact same situation - has CQ and CC and if I want to use TestLInk I must be able to interface at least to CQ.
I would like to know have anybody successfully integrated Clearquest and Testlink. We have recently installed Testlink in our labs and want to integrate with Clearquest. Is this integration supported? If yes it will be great benefit if somebody provide us steps for doing the same.
