Re: Can I use loadrunner 9.5 for recording Peoplesoft 9.2 version?
You can certainly try to record your PeopleSoft 9.2 application using VuGen 9.5 and the Web protocol however given the comment in the LoadRunner 11.52 Readme it appears that you are likely to have a more positive result with the latest version.
Furthermore as the LoadRunner 11.52 Readme indicates support for PeopleSoft 9.1 it is possible that, from a recording perspective, there are no significant differences between 9.1 and 9.2.
Regarding upgrading your 9.5 license to the equivalent for 11.5x, please open a licence case and the licensing team will provide you with an equivalent license for the latest version. There may be no cost impact involved depending on the type of license you have. Note that the license affects load testing using the Controller - VuGen is not a licensed component so you could install LoadRunner 11.52 Patch 1 on a separate client platform to try it out and see what the outcome is when recording/replaying a script against your PeopleSoft 9.2 application.
