Data upgrade
A data upgrade in AX 2012 is about transitioning your existing data to a new version of the software. This process involves checking your current data, cleaning out unnecessary or outdated information, and then converting it to fit the new system's format. This approach ensures that, when you switch to the new version, all your important data is available, organized, and ready to use without issues.
Before you start the data upgrade, you want to ensure that you complete the preupgrade checklist in AX 2012. For more information, see Preupgrade checklist for data upgrade.
