How to Replace Mirrored Drive with a Larger One?

"Can I replace mirrored drive with a larger sized one? I'm using windows 2000's software mirroring. I want to then synchronize the drives and remove the remaining smaller drive and replace that with a larger drive. Then I want to create another partition on the new unallocated space. Is this plan possible? Thought I would ask before I buy my two new large drives."

"I have an Exchange Server that needs more space on the system/boot partition. It is a Dell server with hardware-based mirrored drives. I want to replace mirrored drives with larger capacity drives. Is there an easy way to ghost the drive. I'm a little nervous (probably needlessly) about programs that let you take an online backup since it seems like they alter the boot records in some way (i.e. Acronis TrueImage or Symantec LiveStateRecovery). Does anyone on have feedback on a good program to use or the best way to do this?"

How to replace hardware-based mirrored drive with a larger one?

Hardware-based mirrored drives are RAID 1. If you only want to replace hardware-based mirrored drive with a larger one, just need to replace one of the mirrored drives, which is very simple. If you want to replace hardware-based mirrored drive with a larger one and use full size of larger drive, please create new array and then clone/image source array to the new array. After booting from new array, you can use "Resize/Move partition" feature of EaseUS Partition Master to resize RAID 1 partitions to expand the original size to occupy all space on the new array.
