HireTrack NX uses a different method to despatch and return equipment than HireTrack Eclipse. Each despatch or return utilises a prep bay and a despatch or returns note. During the upgrade process, these items are automatically created for any equipment lists that contain unreturned equipment. This can create an unnecessary overhead if you have many false "late returns". If all your late returns are genuine unreturned equipment, then you have no option but to process them all during the upgrade, however if your late returns are due to poor management of the late returns area of HireTrack Eclipse, then the upgrade process will give you the option to return all equipment that was over due before a specific date. You will therefore need to be aware of how your organisation has dealt with late returns in HireTrack Eclipse.
