Reconfigure Raid5 to Raid1 on DELL PE2650

Hello Guys
I want to reconfigure raid5 and make it raid1 on dell PE2650 and new DELL PE2950 as well
on DELL 2650 I got 5 disks with Raid5 only OS 2003 is there so need only about 15GB on Raid1
ON Dell 2950 I got 5 disks all 146 sas only OS files MS 2008 enterprise edition, which is a node of cluster and got hyper v on there, I want to take out 3 sas drives so i can use them somewhere else as on this server i don't need much space as only need OS that 2*146 drives on Raid1 will be enough,

main purpose is to do it on DELL 2950 but as that critical server so i want to test it on first DELL 2650 that's free for testing.

am thinking to do it via first making a backup using Symmantic or Acronis to external drive, then reconfigure raid on server and keep on two disks raid1, and restore data from backup. is there any issues we can expect in terms of clustering or hyper V, hope not as we will do complete hardware restore backup.

or is there any recommended way doing raid configuration without loosing data using open manage administrator.
I tried on PE2650 but not much luck.

As far as the hardware goes ... you cannot reconfigure to a configuration of less disks (Ie RAID 5 to RAID 1).  You can only Reconfigure to a level using more disks (three-disk RAID 5 to 4-disk RAID 5, RAID 5 to RAID 0, RAID 1 to RAID 5, etc.).  Your only option to make that change is to image and recreate the desired RAID array.

ok just wanted to make sure that with image backup and restore it won't make any issues for Cluster setup and hyper V on this server was configured as clustered application.
this server is a node of cluster connected to DELL MD 3000 storage as well.

Only sure about what the hardware can(n't) do.  I've never had an issue with Hyper-V after image restores, but I'll let a another Expert with experience with clusters address the cluster part of it.  ;)

Finally guys  I have done this by spending bit extra time,
what  I have done is

1. done complete back up using Symmantec exec and full backup using WIN Server backup
2. switch off server took 3 SAS drives out by leaving only 2 SAS drives and configured raid 1 on these two.
3. boot from symmantec cd recovering complete server, looked fine but didnt work and server was not booting up.
4. tried restoring using win server 2008 backup by booting from win svr 2008 os DVD but i would say never use it as ended up with loads meaningless errors.
5. tried again with symmantec by doing some Raid drivers changes and changing drive type etc.
and yes it did work last time and now its online within our cluster network and evrything seems fine in terms of Hyper V and clustering.

anyway thanks for participating in this topic

done by using second option i.e.
Image using Symmantec then raid config and restore.
