Q: Do I need to uninstall the old version of the add-on before I can install a new?
A: No, you just need to install above to old version (the system will automatically trigger an uninstall of the older version before the new 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/Perhaps" and for minor patches (PL) it is not needed? - There are exceptions to this (SAP sometime make changes in smaller patches too that break compatibility but it is rare).
Q: If I upgrade will I loose 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 fixed list of needed changes, but included in the B1UP download is always the most recent list of known needed tweaks so it is always recommended to read this document when upgrading. Our general recommendation is that if if you have configurations that a mission critical to your customer you should test the upgrade in a test-environment first.
Q: Can I always be sure B1UP works on latest SAP version?
A: No, while we sometime get early access to patches B1UP 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 critial to your customer you need to test / write to [email protected] and ask for our experience with a certain patch (please note that it also for use take 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 it's release date)
Q: Is it possible to the downgrade?
A: From a technically 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 never version they might not in the older version
