Hi,

> The help contents in QNX SDP 6.4.1 (For Windows) talks about migration from 6.
> 3 to 6.4.1 and from 6.4.0 to 6.4.1. I could not find information about 
> migration from QNX 6.2 (IDE 2.0) to 6.4.1 (IDE 4.6.0).

That's correct. You will also note that there is no info on migrating from 6.1 to 6.4, or 6.1 to 6.3, or 6.0 to 6.2, etc
. The reason is that it would simply be too much work to provide such information.
 
> Can somebody provide a guide on how to get started with migration from 6.2 to 
> QNX SDP 6.4.1?

First you have to find a BSP for 6.4 that runs on your hardware. If you need to port the BSP (not only your 
applications), you need a 6.4 BSP similar to your hardware. 

Begin migrating drivers one by one, try to compile them. If errors come up, refer to migration notes 6.2 to 6.3 first, 
if it doesn't work, look in 6.3 to 6.4 info. Also with failing function calls, consult the documentation.

There is an alternative: QNX offers Consulting Services for porting. A QNX engineer (or several) could visit you for a 
week or so and help porting. Your QNX Sales Representative can tell you what the cost for this would be.
