To get right to the point, we highly recommend you do not upgrade your business system/ERP until you speak with a TrueCommerce support member.
Upgrading an accounting system could potentially break the existing integration you have between the TrueCommerce platform and your ERP/Business System.
TrueCommerce typically aims to have a compatibility build or full testing against existing builds within 90 days of a new ERP release. However, even with this target deadline, some versions/upgrades are not compatible with the TrueCommerce integration layer.
