We had a lot of fixVersions that we used to identify a time period. We eventually changed the names and removed the old ones from the project. Now we need to report on when epics were moved from the old fixVersion to to the new one (called "Done"). I started with the following JQL:
project = [project key] AND fixVersion WAS "Release One" BEFORE now()
Nothing returns, and I know that there a lot of cases where this happened.
I thought the problem might be that the old fixVersion was no longer in the project, but adding it back in didn't work. And removing BEFORE now() has no impact.
