I have a 1.7.14 installation running on one of our centos 7 clusters and I am interested in updating to 1.8.x to try out the xdmod integration. After backing up all of my config, can I simply yum install ondemand and grab the latest version? Any pitfalls I need to look out for?

Thanks!

I would always refer to the release notes for upgrading to any given version. Search that page for warnings. What pops out to me is enabling an allowlist for ssh hosts, otherwise the shell app will block all the hosts you try to connect to.

Also because we’re in the process of upgrading major versions, blanket updates don’t work right now so you’ll have to run `yum update ondemand` to just update it. Here’s more info on that:

> You have a few options. If you want to update just ondemand: yum update ondemand If you want to update OS you will have to exclude ondemand: yum update --disablerepo=ondemand-web Doing a blanket update will not work at this time due to updates to our latest repo in preparation for building OnDemand 2.0 RPMs. I would strongly recommend not updating to that release at this time because there are numerous breaking changes that we’ve not yet documented. It might be a good idea to switch to OnD…
