Good to know

NEW! Migrate directly from version 14, 15, and 16 to Business Central online
Business Central includes a cloud migration tool that administrators can use to migrate customer data from on-premises databases to Business Central online. Starting now, the Cloud Migration app also supports migration from the earlier on-premises versions of Business Central, with the latest cumulative update applied: Migrate directly from versions 14.x, 15.x, and 16.x to version 17.x. This helps customers reduce their costs of migrating to the Business Central cloud significantly, as they can skip upgrading their on-premises environments to the latest version of Business Central and just migrate the data, including all historical transactions. The Cloud Migration app now includes all the necessary data upgrade logic to convert the data from the previous versions to the data structure of 2020 release wave 2 (version 17.0). Learn more here.

Database size when migrating from Business Central on-prem to online
We have increased the limit we apply to the database size from 30 Gb to 80 Gb when migrating from Business Central on-prem to Business Central online using the Cloud Migration tool. If you are looking at migrating a larger database, we recommend that you contact the support team and work with them to make sure that the migration is successful. Learn more here and read about running the cloud migration tool here.

Apps are moving to office.com

Easy access to production or sandbox environments from the mobile app
Users of mobile devices can now choose between their sandbox and production environments without the need to use the pre-crafted URL as before. Partners running their own apps based on Business Central can also let their users explore it from mobile devices. Learn more here.

Unblock multifactor authentication for mobile apps
We have updated core authentication components of the mobile app to support multifactor authentication. Enabling such flow in the user setting on your Microsoft 365 account and then using it on a mobile device (via an SMS code, authenticator app, or more) is now possible after updating the Business Central mobile app to version 3.0 or higher.
