How important is updating tails/tor

If you have a pack on the way and possibly may need to contact the vendor again can I just not update tails yet or is this dangerous? Last time I updated tails it messed up my tails and I lost all my persistince and I really can't take that risk again. Is this update required for security and privacy purposes?

It is very important. Many of the pedophiles caught using TOR were using old versions with javascript vulnerabilities.

Make an encrypted backup of the persistent data on the machine and copy it to a USB stick.

Hell, make two copies just to be safe.
