Vicibox from 6 to 8 and mixing asterisk versions

[scicali]

Hi, i've a cluster with one db server and three web/telephony server

ViciBox v.6.0.3-141118
SVN: 2972
Asterisk 1.8.32.3-vici

I'd like upgrade to vicibox 8 and asterisk 13, to use viciphone.

I think I can upgrade one server at a time, but remember that a cluster must have same asterisk version... right?

What's the best way? It's a production system..

No, within a cluster you do not have to maintain the same Asterisk versions. We have many clients running multi-server clusters with Asterisk versions from 1.4 to 13.

What you do have to make sure is the same is the VICIdial code version(or svn revision) across all servers in the cluster.
