[SunHELP] root disk transition from veritas to disksuite

[sunhelp at sunhelp.org]

I have an existing disk which had been part of a veritas vm root mirror, but
I've broken the mirror and unencapsulated it.  Going forward I want to
create
a Disksuite mirror and need to make slice 3 and 4 able to be used for metadb
replicas.  Long story short... Can I reduce slice 1 (SWAP) by 10mb and then
map
slice 3 and 4 to use 5mb a peice of these newly freed cylinders, then label
the disk, and not expect to have any trouble?  Would single user mode
suffice
or perhaps I should boot off the cdrom?  Thanks for any tips.
