1 - back up your data
2 - convert to hw raid
3 - test carefully to be sure it works
4 - reload your data

And left out, step zero, consider why you want to do this if what you 
have is working reliably
also, between 2 and 3 consider upgrading to a distribution and kernel 
written this millenium.

Given the state of hardware raid when that kernel was new, and the state 
of the drivers, I would be very sure I had a GOOD reason to change anything.
