Subject: convert legacy array in place?

Hi,
It seems like this should be a FAQ but careful google and mailing list
archive searches didn't seem to turn up anything.
I have two machines with legacy RAID-0 arrays created with raidtools. I
have updated one to Fedora Core 4 and now use mdadm. Am I correct in
thinking I have to use "mdadm --build" every boot to access the array?
My mdadm.conf contains
DEVICES /dev/hda1 /dev/hdb1 /dev/hdc1
ARRAY /dev/md0 level=raid0 num-devices=3
devices=/dev/hda1,/dev/hdb1,/dev/hdc1
but the array doesn't seem to come up by itself on boot.
On the same lines, can this array be converted to a new style array just
by writing new superblocks, or do I have to do the
backup-reformat-restore thing?
TIA.
