  • Still on Dynamics NAV? Your path to Business Central

    Many Australian businesses still run Microsoft Dynamics NAV. It works — until it doesn’t. Here is where support stands in late 2026 and how to plan the move to Dynamics 365 Business Central.

    Where your NAV version stands

    • NAV 2009, 2013, 2013 R2 and 2015: out of support
    • NAV 2016: extended support ended 15 April 2026
    • NAV 2017: extended support ends 12 January 2027
    • NAV 2018: extended support ends 12 January 2028

    Out of support means no security updates or fixes — a growing risk for a system that holds your financial data.

    Two ways to get to Business Central online

    • Full upgrade and migration — all historical data comes across. NAV customisations written in C/AL must be rebuilt as AL extensions. NAV can’t go straight to the cloud: it is upgraded through Business Central on-premises version 14, then a current version, then migrated online.
    • Reimplementation — start fresh in Business Central and bring across master data, opening balances and setup. Often cheaper and cleaner for heavily customised systems, and a chance to adopt standard processes.

    What changes in Business Central online

    • Microsoft updates it twice a year (April and October), with smaller updates in between — you are always on a current version
    • Customisations live in extensions, so updates don’t break your system
    • Integrations move to modern APIs; direct database access and file-system access are not available
    • Australian customer data is stored in Microsoft’s Australian data centres
    • Licences are per user per month (Essentials, Premium and Team Members)

    How to plan the move

    • List your customisations and ask which are still needed — many are now standard or available as AppSource apps
    • Clean up old data before migrating; storage is included per licence
    • Decide how much history you really need in the new system
    • Rebuild key reports and integrations early
    • Plan user training and a realistic go-live — typically 6–8 weeks for small businesses and 10–12 weeks for mid-sized

    If you bought perpetual NAV licences and are on an active enhancement plan, ask about Microsoft’s current migration offers — they can reduce licence costs in the first years.
