We are encountering major issues with our upgrade from 24R2 to 25R1. This is our 3rd Cloud upgrade. The first two painful upgrades we considered these may be teething problems and related to upgrading to the latest version (as IFS recommends by the way).
Now we decided to be conservative and go for 25R1, just one release up and 9 Service Updates rich. IFS also confirmed they have improved supporting these upgrades. Finally, we have customizations but very little (as compared to other clients according to IFS and our implementation partner).
We are now 4 days in the upgrade process and do not even have the build place working with help of IFS. One issue pops up after the other is solved. Did any of you experience similar issues? What else? What more can we expect? Should we go for 25R2? Not upgrade at all? What can you advise?
