My C drive in my SBS 2008 is running out of space and I already followed every single recommendation out there and free'd as much as I could. Unfortunately my configuration was initially set as a RAID 1 250 GB drive and my C drive only has 60GB (crazy..I know)

I am at the point where I would like to migrate from these 2 250 GB to 2 TB and possibly even do a RAID 1 for better performance (I will have an external backup)

WHAT IS THE BEST AND SAFEST WAY TO MIGRATE/CLONE MY RAID 1 DRIVE TO A NEW RAID 0 or RAID 1 1TB Drive?

If you are going to upgrade your drives, I suggest you do NOT change the RAID configuration.
Follow the steps outlined here to do it:
http://blog.mpecsinc.ca/2009/03/sbs-2008-using-sbs-backup-to-expand.html

If you are leery of that, there is a trick I often use for situations like this that works wonderfully!  You can move the winsxs folder (which I'm sure is what's taking up the most space on your C: drive) to another partition, and create a junction link to the new location so that Windows still thinks its on the C: drive.

Use a free tool Junction Link Magic to do this.  

Before moving your winsxs folder, create a test junction link just to make sure you understand the process.

The tried and true method
1. Backup
2. Build a new RAID1 with the new disks.
3. Restore

P.S. there  is NO safe way to use a RAID0.  Period.

You can additionally configure another RAID for your data partition(s) and move those partitions to 2TB RAID.
Then delete the data partitions on 250GB RAID and allocate the all space to system partition. That's easy to do imho.
Or if you data partition is not used much - reallocate some space from data partition to C: partition via resize.
Otherwise - backup - new RAID configured - restore.

Thanks everyone for their input. I will be following the method. I Am curious as to what would be the disadvantage or the advice of "not to" when changing to Raid 1. (beside the RAID differences)

Perhaps you confused us in your initial question?  You stated that you currently are using a RAID 1.

If you are currently using a RAID 0, then you should DEFINITELY switch.  RAID 0 doesn't really give you any recovery options.

Just thought I would give everyone heads up as I always like to see when people share their results. I had to do some extra work as SBS backup restored the partitions exactly as they were and ended up with 700+GB free. This is what I did:

1) Performed a full backup of all Partitions (I had three)
2) Shutdown server and replaced older drives with larger drives
3) On boot up, Delete the existing RAID 1 config.
4) Create a new RAID 1 config with the two new larger drives
5) Inserted SBS 2008 CD 1 and did a restore
6) Once it came up, I used AOMEI partition assistant Server edition (AWESOME) to:
           a) First resize the last partition D to use all the free space
           b) Second to decrease this same partition so the free space is now between C: and D:
           c) Increased C: partition
7) After 30 minutes, I had my lovely 750GB c: drive
I DID HAVE TO REBOOT to get my SQL databse running again

Thanks everyone for your help!
