You'll get a complete guide to migrate Windows Server OS to a new disk with success on this page.

# 1. Prepare New Disk for Windows Server OS Migration

In the process of preparing a new disk for Windows Server migration, you may encounter two issues:

  1. 1. Which type of disk to select?
  2. 2. How to make the new disk ready?

Let's first figure out what your goal for Windows Server OS migration is:

  • Upgrade Windows Server to a bigger disk, hard disk drives with big storage capacity is what you need.
  • To optimize Windows Server running speed, SSDs with sufficient storage capacity should work.

A hard drive with 32GB - 4 TB or SSD with 2-4TB or even bigger storage size is recommended for Windows Server installation.

When you get the disk back, you've now come to the next step: getting the new disk ready for Windows Server migration. Here are the steps:

Step 1. Add new disk to Windows Server computer via a SATA cable and a power cable.

Install new hard drive

Step 2. Once connected the new disk to your computer, open Disk Management in Windows Server.

Open Disk Management

Step 3. Right-click the old system drive and select "Properties", confirm its disk partition style is MBR or GPT. 

Check disk partition style

Step 4. Locate and right-click the new disk, which will display as "Disk unknown not initialized", and select "Initialize Disk". 

Initialize disk

Step 5. Select the disk style for the new disk, make sure it's the same as the old system disk - MBR or GPT, and click "OK" to confirm.

Intialize disk

Once done, your new disk is ready for Windows Server migration, and you can move to the next guide for further operation.
