QNX 6.3 on a Hitachi SH4 custom board

I have a custom board with a Hitachi SH4 processor, I used the Hitachi solution engine BSP and modified it to get started in QNX6.2.1. After I installed QNX 6.3 I have the following problems. The OS image project I used in QNX6.2.1 doesn’t want to build anymore. The IDE says there is no rule to make target ‘I’. I also get some reference problems and other issues when trying to compile programs that worked on 6.2.1 but I am not going to go into the details now. The main question is whether my Board Support Package from QNX6.2.1 can work with QNX6.3?
