Yes, that's the case, but what was nothing which bothered me. I just accepted it.
It is more confusing and not ideal that we have to tweak the backups when upgrading to the new version.
I will look now for the "fix", hope it will work.
But what is about the old backup states in the chain? Will the cleanup work, I mean, the old backups before the last one are not moved to the new place.
Edit:
I moved the latest backup as suggested and then wanted to have a look if the script do the cleanup in the correct way, but the log is not complete.
I backup 2 folders in this job, I can only see the details of the second folder backup, for example which backup states were deleted and which ones were preserved.
