I’m looking at upgrading my install of ignition over the upcoming weekend. My install is on a VM, and I can spin up a second VM for testing and/or upgrade target if needed. I was considering rebuilding the VM anyway to update the OS (ubuntu right now, 14.04.6, so it’s a little behind the times.)
I’m looking for guidance on whether it’s best upgrade a running 7.9 server to 8.0, or if it’s best to install a blank 8.0 server and restore a 7.9 backup. I’m not sure if there is a functional difference. I suppose I could even install 7.9.6 on a fresh VM, restore a gateway backup then upgrade that to 8.0.12 if upgrading is the preferred path.
I don’t think I’ll be able to run both instances at once. I have some devices behind a serial gateway (not modbus gateway, actual serial gateway) that I think will not behave properly if two hosts start trying to request data. Other devices are more modern modbus gateways that I think would be able to keep conversations sorted between multiple hosts. Over the weekend, I’ll have a chance to stop the old gateway and test out version 8 in some fashion. Either snapshot the VM and do an in-place upgrade, or enable comms on a separate VM. Hopefully I’ll have time to sort any issues that pop up before production resumes.
