Major Version Upgradation from 9.4 to 9.6 in Replication Environment

[Quipment Logo]

Hello,

We have a windows setup where we have 2 node primary-slave setup which comprises Async Replication + Log Shipping on slave.

Now we want to upgrade it from 9.4 to 9.6 version.

Do we need to upgrade slave to 9.6, upgrade master to 9.6 and setup replication again from scratch?

What are the best possible ways available to upgrade slave and master without setting up replication again?

Our Setup - WINDOWS SERVER 2012 , PostgreSQL 9.4.7 on primary and slave
Objective - To Upgrade Master and Slave from 9.4 to 9.6

Thanks,
