The upgrade to RELENG_6, from RELENG_5_4, is straightforward and
simple. Comment out these lines in the GENERIC kernel:

makeoptions     DEBUG=-g                # Build kernel with gdb(1) debug symbols

# Debugging for use in -current
options         KDB                     # Enable kernel debugger support.
options         DDB                     # Support DDB.
options         GDB                     # Support remote GDB.
options         INVARIANTS              # Enable calls of extra sanity checking
options         INVARIANT_SUPPORT       # Extra sanity checks of
internal structures, required by INVARIANTS
options         WITNESS                 # Enable checks to detect
deadlocks and cycles
options         WITNESS_SKIPSPIN        # Don't run witness on
spinlocks for speed

Then run all the standard stuff, don't use your 5.x kernel config
