Upgrade older Ignition 7.5.10 to 7.5.14

Hello, I have a customer that will not pay to upgrade to 8.1 and they are using 7.5.10.
They are migrating to a NEW PC, finally, and when I transfer the project to this PC, can I upgrade to 7.5.14, and will it work with the latest version of Java 8 or do I need to install Java 7?

The system requirements for 7.5 say Java 6, 7, or 8 should work.

I’d try Java 8 first, ideally in a test environment.

Thanks Kevin! I will get it all installed and ready, in parallel, with the current system to make sure it’s working correctly before we switch it over.
