I'm working for a company that is upgrading from AX 2009 with an oracle db to AX 2012 with a SQL backend and have been asked to provide baselines against which performance testing can be done. I have outlined that creating what the acceptable performance should be is a requirement and requirements are not created by testers however it fell on deaf ears and I was asked to "have a look online and I'll find other people who have done this kind if thing.." Anyone any suggestions on this?

Thanks in advance.
