Upgrade

[Marc Hoppins]

Hi all,

Looking at upgrading our install from 4.0.3 to 4.0.6.

We have replication from one datacentre to a backup site.  Other than modifying 
the replication config from dc1 to dc2, is there a simple method or command to 
stop replication for a period?

The idea being that, should something go awry, the original install and data 
will be around for us to roll back from.

It's just a minor patch upgrade so all you're really upgrading is the
binaries. In any case, switching off replication is not the recommended
approach. The recommended pre-upgrade procedure is to take backups of the
data on your nodes with nodetool snapshot. Cheers!

On every node?
