Your Guide to Deployment of Dynamics 365 Business Central

Dynamics 365 Business Central was first released by Microsoft in April 2018. Since its first release, Microsoft has continued to enhance the application with regular major upgrades twice per year. Microsoft’s major functional improvements, along with changes in user experience, development tools, programming models, and deployment options has led to an increased number of implementations.

The most recent release of Business Central is the 2019 Release Wave 2, which was released in October 2019. In this blog post, we will be discussing the changes included in the latest Business Central release and differences between deployment options that include either on-premise deployment or SaaS (Software-as-a-Service).

SaaS Deployment

If you choose to implement Business Central as a SaaS deployment, it is important to understand the frequency of upgrades and what the upgrade entails. As part of your subscription, Microsoft automatically pushes out minor upgrades monthly. The upgrades include minor improvements and bug fixes.

Microsoft is able to do automatic upgrades because SaaS deployment does not allow changes to be made directly to the code. Developers perform all customizations through extensions, protecting native code. Historically, companies had to perform time-consuming and possibly costly code merges whenever updates were applied. This step has been removed and allows for a more seamless and timely upgrade.

Microsoft releases major upgrades twice a year, in April and October. Microsoft publishes the known code changes and any necessary resolutions of the code changes ahead of each release. If your environment has existing customizations, there may need to be updates performed on them prior to deploying the major upgrade in order to ensure no problems occur.

On-Premise Deployment

If you choose an on-premise deployment, Microsoft does not automatically push updates to your environment. You are responsible for ensuring both minor updates and major upgrades are performed in a timely manner.

Microsoft recommends following the SaaS cadence of performing minor updates monthly and major upgrades semi-yearly to stay current with new features and bug fixes.

As mentioned above, if your environment has existing customizations, they should be examined to ensure updates do not need to be made prior to deploying the major and minor upgrades.

Business Central Release Wave 2

In the 2019 Release Wave 2, Microsoft has added many enhancements to improve Business Central’s functionality. The following list outlines a few of the new changes included in this release:

System Access

Users can access the system via the browser, mobile apps, Windows 10 desktop application, or in Outlook. In this latest release, Microsoft no longer includes the Dynamics NAV client connected to Business Central. However, the legacy Dynamics NAV client remains supported in the April ’19 updated and earlier versions in alignment with the support lifecycle.

New Development Model

Prior to 2019 Release Wave 2, developers had two different ways of customizing Business Central:

  1. Directly modifying native code or leveraging Event Subscription using C/AL language; changes were done in the C/SIDE environment or
  2. Creating extensions through AL language in the modern source code editor using Visual Studio Code.

In this release, the development environment C/SIDE is deprecated, and all customizations must be done through writing extensions with AL language in Visual Studio Code. We are frequently asked, without the C/SIDE development tool, how can developers explore the native code and native business logic for building extensions around it? To handle this, Microsoft turned the entire application base code into two AL extension apps:

Base Application and System Application. With the native code delivered as an extension and made available on Docker image, you can export the source code from your Docker container environment for direct customization, repackage it, and deploy it back to Business Central.

Enhanced Migration Tools

As more and more customers make the switch from their existing Dynamics NAV, GP, or SL solutions to Business Central, there is a need for better tools for migrating from an on-premise system to the cloud. The 2019 Release Wave 2 features enhancements to the existing migration tools that facilitate an easier switch for legacy Dynamics customers.

Multitasking across multiple pages

This new capability allows users to work on multiple tasks at the same time. You can open a second page in a new tab or page and do multiple tasks at the same time while working in the same company. You can also work with multiple companies in multiple pages, with a colorful company badge indicator identifying the company on each page.
