How to upgrade 2 clustered environments from v7 to v8

FunkyChicken645

Hello, 

How would I go about upgrading two clustered environments from v7.18 to v8.20?

I'm not sure about the order in which to upgrade the servers

Should I upgrade 1, apply redis, then upgrade 2?

Any help would be appreciated!

Hey there, thanks for using the Decisions Community forum!

We actually have some extensive documentation on this:

https://documentation.decisions.com/docs/upgrading-decisions-v7-to-v8

https://documentation.decisions.com/docs/setting-up-redis-external-caching

You're correct in the order of which you'd upgrade the servers, here's some steps laid out for you!

1. Stop server 1 and 2 in the cluster

2. Upgrade server 1

3. Start server 1, and apply redis url from admin console on server

4. upgrade server 2, then start server 2

This should be all you need to do to properly upgrade the clustered environments, feel free to explore our documentation for more information.
