<h2 style="margin-top: 0px; margin-bottom: 10px;">What is included in AOMEI Partition Assistant Server?</h2>
<p style="margin-top: 0px; margin-bottom: 0px;"><strong>Partition Management</strong> – Resize, move, merge, split partitions without data loss.<br /> <strong>OS Migration</strong> – Move Windows Server installations to SSD, boot directly.<br /> <strong>Disk Conversion</strong> – Convert MBR/GPT, dynamic/basic, NTFS/FAT32 without losing data.<br /> <strong>Cloning Tools</strong> – Clone disks or partitions, including larger to smaller.<br /> <strong>Recovery Tools</strong> – Restore lost partitions, files, and repair boot records.<br /> <strong>Core Capacity</strong> – Manages simple, spanned, striped, mirrored and RAID-5 volumes.</p>
<h3 style="margin-top: 30px; margin-bottom: 10px;">What are the main benefits of AOMEI Partition Assistant Server?</h3>
<p style="margin-top: 0px; margin-bottom: 0px;">AOMEI Partition Assistant Server is a disk partition manager licensed for commercial use on Windows Server 2025, 2022, 2019, 2016 and 2012 (R2) as well as Windows 11 to 7 client systems. It combines partitioning, cloning, conversion, cleanup and recovery functions in one console, aimed at small and medium-sized business environments.<br /><br /> <strong>Server OS Support</strong> – Runs on Windows Server 2025 through 2012 R2.<br /> <strong>Commercial Use</strong> – Licensed for business deployment, unlike the free Standard.<br /> <strong>Downtime Reduction</strong> – Extends full system drives without reinstalling Windows Server.<br /> <strong>RAID Volume Handling</strong> – Resizes mirrored, striped and RAID-5 dynamic volumes.<br /> <strong>Emergency Repair</strong> – Bootable WinPE media fixes servers that fail booting.<br /> <strong>Space Cleanup</strong> – App Mover and junk cleaner relieve full drives.</p>
<h3 style="margin-top: 30px; margin-bottom: 10px;">What does AOMEI Partition Assistant Server actually do?</h3>
<p style="margin-top: 0px; margin-bottom: 0px;">It manages hard disk partitions on Windows Server and Windows PC systems without destroying the data on them. A typical case is a full C: drive on a production server: the built-in Extend Partition Wizard takes free space from other partitions on the same disk and adds it to the system volume, which Windows Disk Management often cannot do because its "Extend Volume" option requires contiguous unallocated space. Beyond resizing, it migrates the operating system to an SSD, clones entire disks, converts disks between MBR and GPT, and recovers deleted partitions. All core operations are wizard-driven, so they can be performed without diskpart command-line work.</p>
<h3 style="margin-top: 30px; margin-bottom: 10px;">Who is AOMEI Partition Assistant Server best suited for?</h3>
<p style="margin-top: 0px; margin-bottom: 0px;">It is built for administrators in small and medium-sized businesses who run one or two physical Windows Server machines, since one license activates the software on 2 servers or PCs. The practical advantage over the free Standard edition is concrete: Standard neither installs on Server operating systems nor permits business use, so a file server with a shrinking system partition cannot legally or technically be fixed with it. The Server edition also handles dynamic disk volumes, including software RAID-5 and mirrored volumes, which consumer partition tools typically exclude. Companies that need to cover many machines should look at the Unlimited edition instead.</p>
<h3 style="margin-top: 30px; margin-bottom: 10px;">How does the Server edition compare to Professional, Unlimited and Technician?</h3>
<p style="margin-top: 0px; margin-bottom: 0px;">The feature set for disk operations is largely identical across the paid editions; the differences are operating system coverage and license scope. Professional costs less but does not install on Windows Server operating systems, so it only fits client PCs. Unlimited covers unlimited machines within one company and adds a portable version that runs from a USB stick without installation, while Technician additionally allows billable services for external clients. The official comparison is summarized below.</p>

<h3 style="margin-top: 30px; margin-bottom: 10px;">Can it extend a full C: drive when Disk Management cannot?</h3>
<p style="margin-top: 0px; margin-bottom: 0px;">Yes, this is one of its core use cases. Windows Disk Management requires unallocated space directly adjacent to the volume being extended, which is rarely available on a production server, so "Extend Volume" is frequently greyed out. AOMEI Partition Assistant Server solves this with "Move Partition", which shifts partitions to consolidate free space, and with "Allocate Free Space", which transfers space from a data partition such as D: straight into C:. The operation runs without formatting and without data loss, so a database or Exchange server with a full system drive can be repartitioned instead of rebuilt.</p>
<h3 style="margin-top: 30px; margin-bottom: 10px;">Can I clone a larger server HDD to a smaller SSD and still boot?</h3>
<p style="margin-top: 0px; margin-bottom: 0px;">Yes, cloning from a larger disk to a smaller SSD is supported as long as the used space on the source drive does not exceed the capacity of the destination SSD. The clone includes the operating system, boot sector and all data, so the server can boot directly from the new drive after the swap. This matters in practice because server HDDs are often far larger than the data they hold, and buying an equally large SSD just to satisfy a 1:1 cloning requirement would be unnecessary cost. The "Migrate OS to SSD" function offers a narrower alternative that moves only the system partitions.</p>
<h3 style="margin-top: 30px; margin-bottom: 10px;">What can it do when a server no longer boots?</h3>
<p style="margin-top: 0px; margin-bottom: 0px;">The software can create bootable WinPE media on a USB drive, which starts the failed machine independently of the damaged Windows installation. From that environment, the Boot Repair tool fixes damaged or missing BCD files, Rebuild MBR repairs a corrupted Master Boot Record, and the surface test locates bad sectors. The Partition Recovery wizard restores partitions deleted by accident, hardware faults or malware, and a separate data recovery function retrieves deleted files. These tools reduce the chance that a boot failure turns into a full reinstall, but they do not replace a backup strategy for genuine disk failures.</p>

<h3 style="margin-top: 30px; margin-bottom: 10px;">What technical limitations should buyers know before choosing the Server edition?</h3>
<p style="margin-top: 0px; margin-bottom: 0px;">The Server edition does not include the portable version that runs from a USB stick without installation; that capability is reserved for the Unlimited and Technician editions, which matters for admins who service changing machines. Its license also covers 2 servers or PCs, so environments with more machines need Unlimited rather than multiple Server licenses. Cloning a larger disk to a smaller one only works when the used data fits on the target drive. Finally, it is Windows-only software: Linux file systems and macOS disks are not part of the official platform scope, so mixed server rooms need separate tooling for those machines.</p>
<h3 style="margin-top: 30px; margin-bottom: 10px;">Frequently asked questions about AOMEI Partition Assistant Server</h3>
<h3 style="margin-top: 30px; margin-bottom: 10px;">Does it work with BitLocker-encrypted partitions?</h3>
<p style="margin-top: 0px; margin-bottom: 0px;">Yes, the software can resize and move BitLocker-encrypted NTFS or FAT32 partitions without removing the encryption first. It also includes a BitLocker tool that enables and manages encryption even on Windows Home editions, which normally lack this feature.</p>
<h3 style="margin-top: 30px; margin-bottom: 10px;">Can it securely erase drives before decommissioning?</h3>
<p style="margin-top: 0px; margin-bottom: 0px;">Yes, the SSD Secure Erase Wizard resets SSDs from Samsung, Intel, Kingston and other major brands to factory state, while the wipe and file-shredding functions overwrite HDD data so it cannot be restored with recovery software. This is relevant when retired company drives leave the building.</p>
<h3 style="margin-top: 30px; margin-bottom: 10px;">Does it support virtual disks?</h3>
<p style="margin-top: 0px; margin-bottom: 0px;">Yes, it can create, attach and detach VHD and VHDX virtual hard disks directly from the console. Attached virtual disks can then be partitioned and managed like physical drives, which is useful for test environments and Hyper-V-related storage tasks.</p>
