Note: If the source environment contains any QAD add-on products, you must check their compatibility with QAD Enterprise Edition 2017 before performing the upgrade. If any add-on products need to be updated as part of this upgrade, refer to the individual add-on product guides as reference. QAD recommends that all QAD add-on products be installed using a delayed install to allow all products to be configured simultaneously when executing the final yab update.
