compatibility between RTC 5.0.2 and Report Builder 6.0

Yes, you can use RB 6.0 with CLM 5.0.2, but as I understand it, the supported mechanism is to use Install Manager to install RB 6.0 (as well as a 6.0 JTS), and not to copy the .war around as you describe.

I'm pretty sure that IBM does not support such mixing. 

Hello David,

I would suggest the following procedure to achieve what you want to do:
1) Upgrade JTS 5.0.2 to 6.0 (as this is a requirement to run any 6.0 application).
2a) If you already have report builder 5.0.2 installed upgrade it to 6.0.
2b) If not, install report builder 6.0 and register it to the upgraded JTS.
3) The remaining applications can stay on 5.0.2 level until you decide to complete the upgrade.

thank you for all your answer.
It's a good new to use RB 6.0.

Best regards
