I’ve tried installing a gateway from all the way back at 8.1.1 to both 8.1.44. I get stuck on the screen Ignition Gateway is UNKNOWN. If i eventually stop it, I can’t get the service to run again and need to do a reinstall. Is there a version somewhere in between that I should update to first? I’ve looked to see if there were any issues with past versions but I’m not finding any. ---

No, that shouldn't be necessary. Share your wrapper.log files when the Gateway fails to start. ---

It will be a "wrapper.java.additional" line that references "UseConcMarkSweepGC". ---

You can delete 1, 2, and 4. You can also reasonably delete the COMMENTED 7 and 8 (debug and Xrunjdwp). Feel free to fix all the numbering afterwards, though it's not strictly necessary. Just make sure you don't have any duplicate numbers.
