Acumatica 2022 R2 includes 60+ new features and over 250+ enhancements across the product suite. As Ali Jani, Chief Product Officer at Acumatica, said during the virtual product launch, version 2022 R2 includes more features based on customer feedback than any previous release. This is the direct result of Acumatica product managers visiting with customers to see how they are using the product. Customer use cases are at the foundation of Acumatica’s product innovations.

To learn more about Acumatica Cloud ERP and What’s New in Acumatica 2022 R2, visit the Acumatica Resource Center.

As with any major release, it is important to read the release notes and fully test the upgrade before applying it to your production environment. For Acumatica SaaS customers, an upgrade sandbox is provided by the publisher as well as the performance of the production upgrade.  It is the responsibility of the customer to perform pre-upgrade testing.  The system requirements below apply to customers that are self-hosted.

Multiple breaking changes have been made to Acumatica 2022 R2 that impact reports, customizations, and integrations that were implemented in prior versions. The complete list of these changes is provided in the Reference List of Changes in the Release Notes document.

Acumatica has outlined the following system requirements to run Acumatica 2022 R2. Please note, these system requirements are subject to change, so please refer to Acumatica Community (login required) or the help files for the most up-to-date requirements.

Before upgrading your current Acumatica Cloud ERP instance, we strongly recommend that an administrator back up all Acumatica configuration files and databases. For a detailed description of how to update Acumatica Cloud ERP, see “Updating Acumatica ERP” in the Installation Guide which can also be found on the Acumatica Community forum.

There are three components of Acumatica ERP to consider prior to upgrade:

  • Web interface accessed through workstations and other user devices
  • Application Server/Web Server
  • Database Engine

For Acumatica 2022 R2, each of these components must meet or exceed the system requirements outlined in this post.

Special Notes

Internet Explorer Support Ended June 15, 2022

Releases of Acumatica prior to June 15, 2022 will provide support for Internet Explorer, but all releases on or after June 15 will not. However, Acumatica Cloud ERP will continue to support Microsoft Edge, Firefox, Google Chrome, and Apple Safari.

Azure Cloud Services – Classic Support Retired

On August 24, 2021, Microsoft announced plans to retire the Cloud Services (classic) deployment model effective August 31, 2024. As of April 5, 2021, the new Azure Cloud Services deployment model is generally available.

Starting with Acumatica 2022 R1, users cannot use the Cloud Service Classic deployment model, as Acumatica is switching to the new deployment model and is no longer providing the following:

  • Azure service package file
  • Ability to generate .cscfg files through the Configuration Wizard

To deploy Acumatica 2022 R1 or later on the Windows Azure platform, users will need to create a Windows virtual machine in the Azure portal and follow the instructions for installing Acumatica locally.



Workstations or devices used to access Acumatica Cloud ERP should meet or exceed the hardware and software requirements listed below:

Hardware and Software Requirements

  • Minimum display resolution of 1024×768, the typical display resolution of 1920×1080
  • Adobe Reader 2019 or later to open Acumatica ERP PDFs
  • Microsoft Office (to view documents exported from Acumatica ERP)
    • Microsoft Office
      • 2019
      • 2016
      • 2013
      • 2010
      • 2007
      • 2003 with the Microsoft Office 2007 compatibility pack
    • Web Browsers
      • Microsoft Edge 44 or later
      • Mozilla Firefox 82 or later
      • Apple Safari 12 or later
      • Google Chrome 87 or later

 Note:  Starting on June 15, 2022, Internet Explorer will no longer be supported by any Acumatica ERP version.

Application/Web Server

The environment where you install the server part of the Acumatica ERP should meet the hardware and software requirements listed below.

Hardware/Software Requirements

  • Operating systems
    • Windows Server 2019 64-bit Edition
    • Windows Server 2016 64-bit Edition
    • Windows Server 2012 64-bit Edition
    • Windows Server 2012 R2 64-bit Edition
    • Windows Server 2008 64-bit edition
    • Windows Server 2008 R2 64-bit edition

Note: You can install the server part of Acumatica ERP on non-server operating systems, such as Windows Vista 64-bit edition, Windows 7.0 64-bit edition, Windows 8.0 64-bit edition, Windows 8.1 64-bit edition, and Windows 10 64-bit edition, but only for testing purposes. For production, you must use a server operating system. No, Windows 11 is not currently supported. I inquired with Acumatica support and they said desktop operating systems were not a primary concern. If I did install Acumatica on a Windows 11 computer, they would support me.

  • Microsoft .NET Framework 4.8
  • Microsoft .NET Core 3.1
  • Microsoft Internet Information Services 7.0, 7.5, 8.0, 8.5, or 10 depending on the underlying operating system.

Note: You must set the Enable 32-bit Applications option to False in IIS settings. Acumatica ERP 2022 R2 supports only the Integrated mode of the application pool. Classic mode is not supported. If you try to upgrade an earlier version of Acumatica ERP using Classic mode for the application pool, the upgrade to Acumatica 2022 R1 will display an error message and fail.

  • Memory: 16 GB RAM
  • CPU: 2 cores; 3.5 GHz
  • Hard Disk Space:1 GB available hard disk space plus 200 MB for each additional instance of Acumatica ERP

Database Engine

You can find system requirements for the database you are using with Acumatica ERP below. Keep in mind that these are minimum requirements. Your installation should be sized based on expected performance and storage needs. Review the typical hardware configuration for PCS and PCP licenses before proceeding.

  • Microsoft SQL Server
    • 2019
    • 2017
    • 2016
  • MySQL Community Edition Server
    • 5.7 or 8.0 64-bit edition
  • Memory
    • 8 GB RAM
  • CPU
    • 2 cores; 2 GHz
  • Hard Disks Space: For each database, 1 GB of available hard disk space. Depending on the number of transactions, additional hard disk space may be required to store large numbers of transactions.

Code Authoring Environments

To create stand-alone applications with Acumatica ERP or develop customizations and add-on solutions on top of Acumatica ERP, you need one of the integrated development environments (IDEs) listed below.

  • Microsoft Visual Studio with Microsoft Web Developer Tools
    • 2019: Community, Professional, or Enterprise edition

Configuring Web Server (IIS) Features

Before you install the Acumatica ERP server software, make sure that the following Web Server (IIS) features are turned on:

  • Web Management Tools > IIS Management Console
  • World Wide Web Services > Application Development Features > .NET Extensibility
  • World Wide Web Services > Application Development Features > ASP.NET
  • World Wide Web Services > Application Development Features > ISAPI Extensions
  • World Wide Web Services > Application Development Features > ISAPI Filters
  • World Wide Web Services > Common HTTP Features > Default Document
  • World Wide Web Services > Common HTTP Features > Static Content
  • World Wide Web Services > Performance Features > Dynamic Content Compression
  • World Wide Web Services > Performance Features > Static Content Compression
  • World Wide Web Services > Security > Request Filtering

Note: Make sure each application pool you are planning to use with Acumatica Cloud ERP 2022 R2 or later has the Enable 32-bit Applications parameter set to False. The parameter is located under the IIS Manager > Application Pools > Edit Application Pool > Advanced Settings menu.

Setting Up an HTTPS Service in Web Server (IIS)

HTTPS is a secure communications channel used to exchange information between a client computer and a server. You may need to set up an HTTPS service for the Web Server (IIS) – for example, if your users export data to Microsoft Excel and want to update the data automatically, or you want to use single sign-on (SSO).

To enable SSL (Secure Sockets Layer) for the Web Server (IIS), you must first obtain a certificate that is used to encrypt and decrypt the information that is transferred over the network. You receive a certificate file from a certification authority, and then register the certificate with your Web Server (IIS). For instructions, refer to the documentation provided with your Web Server (IIS).

Acumatica does not support self-signed certificate.

Enabling Semantic Search for Microsoft SQL Server

To access the full-text search functionality, you must install Semantic Search on the Microsoft SQL Server. For more information on searching in Acumatica ERP, see Building Search Indexes in the Acumatica ERP System Administration Guide or online help.

To install Semantic Search, select Full-Text and Semantic Extractions for Search on the Features to Install page during Microsoft SQL Server setup. For additional details, see the documentation that accompanies Microsoft SQL Server.

Prerequisite Steps

The Apply Updates (SM203510) form in Acumatica only lists minor updates for the currently installed version of Acumatica Cloud ERP. The administrator should manually upgrade the currently installed major version of Acumatica ERP on the server to Acumatica 2022 R2.

Please Note: Using the web interface to upgrade to Acumatica 2022 R1 is not supported.

Before administrators install or upgrade to Acumatica Cloud ERP 2022 R2, they must complete the following:

  • Switch the Internet Information Services application pool where the Acumatica Cloud ERP 2022 R2 instance will be installed to Integrated mode. Acumatica 2022 R2 does not support Classic mode.
