Migrating from ARM 7 TDMI to Cortec M3 or M4

I am beginning to have a situation...  The NXP LPC2148 microcontroller we have used and developed for several years has reached the "Not Recommended for New Design" stage.  This means I have some time to work on the replacement of the micro but not unlimited time.


What I would like to do is migrate to the ARM Cortex family, especially the M3 or M4 variant.  The problem I have found is there seems to be very little documentation regarding this process.  Somewhere there must be some information,examples and/or recommendations regarding the migration from the ARM 7 to The ARM Cortex family.


Do you have any information?  Can you point me in the direction of some information?
