Current Architecture
Primary Hot Standby
Postgresql 9.3 Postgresql 9.3
DB Size 1.4 TB Database Size 1.4 TB
Want to upgrade both primary and hot Standby to 9.4 at same time. I m not able to figure out how to upgrade Hot standby and primary simultaneously. What ever I have read so far only tells me about upgrading primary which I am able to do it . Can anyone please guide me How to upgrade Secondary database so that I don’t have to build standby again from the scratch after upgrading primary database?
Thanks
