[CentOS] migration considerations

I've got a 3ware 9550SX-4LP on a dual xeon 3.6GHz machine (no HVM
possible). 4 SATA-HDs in RAID 5 installed.
xen 3.0.3 with centos-4.4 as xen0. centos-4.4 is also installed on the
numerous xenUs. The xenUs are installed in LVs which are formatted as xfs.
Now I'd like to move over to centos 5.0
This is what I thought to be good as an upgrade procedure:
1) install a xen0 to a (bootable) USB hard disk
this allows me to go back to my old configuration as soon as I
encounter irresolvable probs
2) mount xenU-partitions from xen0 and put modules from the
centos5-supplied kernel in there
with this test I also test if the 3w_9xxx driver runs smoothly, I'll
3) run xenUs and test them (Will they run and work?)
4) if all runs good, install xen0 over the old xen0, make backup before.
My particular question here is: As it's important to have the 3w_9xxx
driver properly loaded with this step, is there anything special I
shouldn't forget here?
All this shouldn't take me more than 2 hours.
What's your opinion? Any more hints?
