No Reinstallation – Upgrade to a larger or faster drive.
Full Space Use – Allocate free space between existing partitions directly.
Safer Conversions – Switch MBR to GPT without deleting partitions.
Preview First – Pending operations are shown before being applied.
Windows To Go – Create a portable Windows on USB.
Broad Hardware Support – HDD, SSD, external drives, hardware RAID.

What does AOMEI Partition Assistant Professional do?

AOMEI Partition Assistant Professional manages disks and partitions on Windows 11, 10, 8.1, 8 and 7 PCs, including resizing, moving, merging, splitting, formatting and cloning. Its practical strength is solving the situations Windows Disk Management cannot handle, such as extending a full C: drive when the free space is not directly adjacent. The Allocate Free Space function moves unused capacity from one partition to another in a single operation, which is the typical fix when a system partition fills up while a data partition stays half empty. It also includes disk health checks, bad sector scans and a disk speed test for diagnosing aging drives before they fail.

How does Professional differ from the free Standard edition?

The free Standard edition covers basic partition tasks, while Professional adds the functions most upgrade and rescue scenarios depend on. OS migration to SSD, converting a system disk between MBR and GPT, allocating free space between partitions, dynamic disk management and partition recovery are reserved for the Professional tier. One Professional license covers two PCs, which matters for households or offices running a desktop and a laptop. Neither edition runs on Windows Server; that requires the Server edition.

Can I migrate Windows to a new SSD without reinstalling?

Yes, the Migrate OS wizard copies the system partition and boot files to a new HDD or SSD so the computer starts from the new drive without reinstalling Windows or applications. This is the typical workflow when replacing a slow hard drive with an SSD in an older laptop or desktop. The wizard also handles the common case where the target SSD is smaller than the source disk, as long as the used data fits. A separate 4K alignment function optimizes SSD read and write performance after migration.

Can it recover lost partitions or deleted files?

The Professional edition includes a Partition Recovery wizard that scans a disk for partitions lost through accidental deletion, repartitioning mistakes or partition table damage, and restores them with their contents. A separate file recovery function targets individually deleted files. Recovery tools are reactive by nature: they help after the damage is done, and success depends on whether the lost area has been overwritten. For irreplaceable data, partition recovery should complement a backup routine, not replace it.

Does AOMEI Partition Assistant Professional support Windows Server?

No, the Professional edition runs on Windows 11, 10, 8.1, 8 and 7 only and will not manage machines running Windows Server 2025, 2022, 2019, 2016 or 2012. AOMEI reserves server operating systems for the Server, Unlimited and Technician editions. This matters for small businesses: managing workstations with Professional is fine, but a file server or domain controller needs the Server edition. Anyone providing paid disk-management services to clients is directed by AOMEI to the Technician edition.

What should users check before choosing the Professional edition?

First, confirm that every machine to be managed runs a desktop version of Windows between 7 and 11, since server systems are excluded. Second, check the hardware: the software supports HDDs, SSDs and SSHDs, external USB drives, flash media and hardware RAID arrays including RAID 0, 1, 5 and 10, so unusual storage setups are usually covered. Third, users who only need basic resizing or merging can test the free Standard edition first, because Professional only pays off when migration, conversion, free-space allocation or recovery functions are needed. Operations are queued as pending tasks and only executed after confirmation, which reduces the risk of applying a wrong change.

Frequently asked questions about AOMEI Partition Assistant Professional

Is there a way to test the software before buying?

AOMEI offers a demo version of the Professional edition that lets you explore all functions, but it only simulates operations and does not apply changes to the disk. The full version is required to execute the queued tasks. AOMEI additionally backs purchases with a 90-day money-back guarantee.

Can it manage disks when Windows no longer starts?

Yes, the Professional edition can create bootable WinPE media on a USB stick or CD, so partitioning, cloning and repair tools remain usable outside Windows. Combined with the Rebuild MBR and boot repair functions, this is the standard way to fix a PC that fails to boot after a partition error.

Does it run on both computers in a household or office?

One Professional license covers two PCs according to AOMEI's official edition comparison. This makes it practical to maintain a desktop and a laptop with a single purchase, as long as both run a supported desktop Windows version.
