iS RTC 6.0.6 can be integrated with RQM 6.0.2 ??

One answer

You would need to elaborate more on what type of integration this question is about.
1. OSLC based integration - There is no version matching checked. So as long as both the app are OSLC compliant, any versions should be compatible.
2. RQM automated tests files are hosted on RTC - for this RTC ( with version N) supports up to N-1 version of Client (RQM). Since I your case both are for major version 6.x.x.x so it should be supported as well.
