Q: Do I need to uninstall the old version of the add-on before I can install a new one?
A: No, you just need to install a higher version on top of the old version (the system will automatically trigger an uninstall of the older version before the new one is installed)
Q: When I upgrade SAP, do I always need to upgrade B1UP?
A: In general if it is a major SAP upgrade then "Yes" and for minor patches (PL) it is not needed - There are exceptions to this (SAP sometimes makes changes in smaller patches too that break compatibility but it is rare).
Q: If I upgrade will I lose my configurations?
Q: Do I need to change any of my configurations when I upgrade?
A: It depends on a lot of factors. In general, when you just upgrade B1UP no changes are needed, but because many people upgrade both SAP and B1UP at the same time certain tweaks to configurations might be needed (due to visual and feature changes in the SAP Client). Due to the dynamic nature of B1UP, there is no finite list of needed changes.
Q: Can I always be sure B1UP works on the latest SAP version?
A: No; B1UP's dynamic nature makes it impossible to test all features in all combinations on new patches, so while we 95% of the time work with new issues only time will tell. If you are unsure and features are mission-critical to your customer you need to log a support ticket and ask for our experience with a certain patch (please note that it also for use takes a bit of time to test a patch and get in known issue so do not expect we can tell if a patch is good or bad on its release date.)
Q: Is it possible to downgrade B1UP?
A: From a technical aspect it is possible but not recommended unless absolutely needed. It is a bit tricky as you need to uninstall the too-high version before you can apply the lower version. Also, if you began using features from the newer version they might not be in the older version.
