Migrating 2 disks RAID1 from opensuse to OMV3.x is possible on a HP PROLIANT MICROSERVER G1610T?

Hi to all.
I'm a newby on OMV.
Untill yesterday I've got a microserver HP N40L with a RAID 1 software (2 disks WD RED 3TB).
Now I installed OMV3 on a new HP microserver G1610T and I DID NOT touch the configuration of the internal raid B120something.
Can I simply move the 2 disks from the old server to the new one and then adding them into the OMV?
Have I to activate the internal raid B120?
Thanks and sorry for the - stupid - question.

Solved by myself disabling del internal RAID hardware of the HP server, enabling the AHCI sata controller and then inserting the 2 disks and mount them in OMV.
