We are using a customized version of RTC 2.0.0.2 iFix3 for our project tracking. We have added new functionality on top of vanilla RTC by building custom Jazz plug-ins.
Some of these plug-ins contain eCore extensions using which we have extended the set of data we store in the Jazz repository.

When we migrate to RTC 3.x - will the eCore extensions be migrated as-is? Is there any guidance available in this area?
