We migrated HP PPM from version 8 (1 node) to version 9.13 (2 nodes). Since, the sequence of lines during a migration does not work. Migrated line by line, the package can be deployed. However, once there is more than one line to migrate at the same time, the first line work (succeeded) but the others lines don't (failed). See attachment1.jpg.
The execution log is also very surprising. See attachment2.jpg.
The first stage is marked both "Succeeded" and "Failed". The execution log of the line shows a success.
The sequence of tasks seems to be in trouble. However, the <<environment check>> works well.
