Instructions to copy persistence miss a step to reactivate the persistent features

I’m dumping here what was reported to us on https://mailman.boum.org/pipermail/tails-ux/2018-July/003563.html:

There is just an instruction missing in the documentation book when you finish to move your persistent datas to another usb key... 
Once you start from the new usb key, you just need to go to Applications > System tools > and Configure persistent volume. 
Now you can check all the datas you want to be persistent at the next start.

But I haven’t tested it myself.
