We are using QC 8.2 SP1. I wrote few functions in VBA (Excel Macros) and used QC OTA APIs to perform few tasks in QC.

If we upgrade the QC to later versions, will these functions work fine? Or I have to update these functions as well to make them work?

And, Currently in Excel references I have added "OTA COM8.0 Type Library". If I upgrade QC, do we have to change in the references also?

Please let me know if I have to provide you more information?
