3-node cluster 5.7.28 -> 5.7.29

[Marco Shaw]

First time I ever try to upgrade my recently new 3-node XtraDB cluster.

I'm also going to upgrade Xtrabackup at the same time (2.4.12 -> 2.4.20).

Should I:

1. Upgrade one node at a time? Take one down, upgrade, restart...

2. Upgrade all at the same time? Take all down, upgrade, restart...

I've modified my installation a bit...  I've got Percona installed in a chroot on an encrypted file system.  I'm guessing this won't have any impact on the upgrade.  I did try an upgrade on a single copied VM, and it seemed to go perfectly fine.
