I am moving in bulk issues from 1 project to the other.
1. Today when I moved the 1st project I encountered a weird behavior.
- I selected that the issue type will be changed from a task to a subtask
- there was a select, where I chose the parent on a new board
- after the move was completed all those issues were not on the new board
- I could find them in the Issues section, however none of them had a parent (which is weird, since all subtasks have to have a parent)
- I solved this problem by bulk editing those issues - adding a parent to them
2. After the 1st point, I started moving the second project the same way, which gave me an error of 500.
