RAID migration

[Anthony Chavez]

Dear freebsd-questions,

I have a HighPoint 1820 RAID controller that is using 1 channel for an
OS drive and 3 channels for a RAID-5 array.  I'm interested in migrating
to a new (possibly non-HighPoint) card, and am wondering if I will be
able to plug the OS drive into one channel on the new card and have it
"just work."  Is it a safe bet that it will?

I'm curious to know if the array could be migrated just as easily, or if
I should listen to my instinct and count on bumping into
incompatibilities due to proprietary implementations.

Here are the relevant dmesg lines of my system as it stands:

hptrr: HPT RocketRAID controller driver v1.1 (Jun  7 2008 14:01:57)
hptmv0: <RocketRAID 182x SATA Controller> mem 0xf2000000-0xf207ffff irq
