Best Software to Clone Windows Server 2019 Disk

A common method to migrate Windows Server from one disk to another is system image backup and recovery - it does work in some cases, and you can accomplish it with the built-in utility Windows Server Backup. However, since the operation involves both backup and restore, it makes the process more complicated, and more error-prone.

In contrast, a direct disk cloning can make things much easier, but Microsoft doesn't offer this function. Fortunately, the professional cloning software - AOMEI Backupper Server can fill the gap of Windows features. It has an user-friendly interface and can clone disk in Windows Server 2019 with the following benefits:

It provides Disk Clone, System Clone, and Partition Clone features. You can choose based on your own needs.

It allows you to clone larger drive to smaller drive as long as the target drive can hold all the used sectors.

When cloning smaller drive to a larger one, you can also edit partitions to make full use of the disk capacity.

It supports cloning both MBR and GPT partition styles, you can choose to convert partition style or clone between different partition styles directly.

Besides Windows Server 2019, this tool also supports Windows Server 2022, 2019, 2016, 2012, 2011, 2008, 2003 (including R2), SBS 2011, 2008, 2003, 2008 and Windows PC systems.

There are some useful options to optimize the cloning.

👉To make full use of disk capacity, you can use Edit Partitions to resize partitions, it offers the following options:

  • Copy without resizing partitions: It will not resize the partition size.
  • Add unused space to all partitions: Reallocate the unused space to each partition of the target disk accordingly.
  • Manually adjust partition size: It allows you to extend unallocated space to any partition on the destination disk you want. And it requires you to manually adjust the size of the partition.

👉Sector By Sector Clone will copy every sector, whether it is used or not. There is a requirement that the destination disk must be equal to or larger than the source disk. If you don't tick this option, the default mode is intelligent clone, which will copy only used sectors to save space.

👉SSD Alignment will improve the working performance of the SSD. If the destination disk is SSD, it is strongly recommended to choose this option.

👉Partition Style (GPT or MBR) help Windows understand how to access the data on the disk. And the partition style of a disk should be compatible with the boot mode (MBR for Legacy BIOS and GPT for UEFI) to ensure the secure boot.

If you purchased a NVMe SSD, it should be partitioned with GPT to support UEFI boot; if it's a SATA SSD, there should be no strict requirements about partition style and boot mode. With AOMEI Backupper to convert partition style or keep the partition style of the target disk as you need.

How to Boot Windows Server 2019 from Cloned Hard Drive

After cloning, you can shutdown the machine to replace the old hard drive with the new one.

If you have confirmed that the server can be started from the cloned drive, you can also attach the old hard drive as a secondary storage - just press the specific key (depends on manufacturer) during startup to enter BIOS, make sure the first boot options is the cloned drive. After that, you can also wipe the hard drive to get more storage space.

BIOS Boot Order

Note that if the partition style of your target drive is different from the source hard drive (such as cloning MBR to GPT), then you also need to change the boot mode in BIOS to make it compatible with the partition style, Legacy for MBR and UEFI for GPT.
