How does Basis Technologies advise on progressing with upgrading a SAP system with Testimony installed?
Firstly you should ensure the Testimony enhancements are deactivated before starting any upgrade processes. See HOW DO I: Ensure Testimony Enhancements are deactivated?
During the upgrade you will likely see the Basis Technologies enhancements in the /BTI/ namespace in the SPAU_ENH after the SAP upgrade.
Basis Technologies can supply the repair key so that you can move forward with the SPAU_ENH, during regular upgrades the enhancements just need to be accepted as they are.
After upgrading you should check that Testimony can record and playback as expected, paying attention to the activation of both the recording and playback enhancements. If you have any problems or notice anything different you should contact Basis Technologies.
Note if you are upgrading to NW 7.53 you will require some new Testimony transports to enable Testimony to cater for this NW version. You should contact Basis Technologies for details on this.
