Sorry, it looks like the UI and report feature will appear only in 0.16.
It is related to HADOOP-1604.
In general you are not supposed to remove any directories manually.
You should just use finalizeUpgrade.
The way it works in pre 0.16 is that you start the cluster, and issue:
hadoop dfsadmin -finalizeUpgrade
Now, if you still want to do it manually, then yes just remove "previous"
dir on the name-node and then start the cluster.
Data-nodes will finalize automatically.
Is it what you were asking?

No sign of 'upgrade still needs to be finalized' or something ...so I
assume removing the 'previous' dir is safe then?

run?
Yes, you can see it on the name-node web UI, and by running
hadoop dfsadmin -report
