Moving a raid array to new computer

[StevenHickerson]

Hey everyone,
I have a question about raid arrays and moving them to a new computer. How difficult is it? I'm about to redo my hard drive configuration in my current system to have a raid 5 setup on my storage disks so that there is less risk of me lossing anything important, but I plan sometime in the next few months to build a new system.

So my concern is transfering this array to the new computer. I'm going to have my OS drive on a seperate either R0 or single drive non raided, the R5 array is going to be storage only. Will I be able to recreate the r5 array when I build the new computer without loosing the data on it, or will I have to backup all the data in order to rebuild the array and then copy the data over?

This is where the problem comes in because the array I'm building is going to be 4 2tb drives, so 6tbs of space, and I have at least 3 TBs of data right now that will be on them, so backing it up is a huge pain, it took me using every spare hdd I had just to get all the data backed up now in order to wipe the drives and build the array to begin with lol.

Thanks for any answers!
