I'm having a problem on a new computer. I installed v8.1.41 and restored a v8.1 gateway backup. Everything seems fine. Then I restored a v7.9.10 backup on this new gateway and during the restore process, the gateway won't restart. I've uninstalled and re-installed the v8.1.41 ignition and repeated the process several times. Every time I get the same result and the windows System Event Viewer Logs shows "The Ignition service terminated with the following service-specific error: Incorrect function". Any help would be greatly appreciated. ---

Can you upload your wrapper.log file after having restored the 7.9.10 backup? ---

I can, but I don't know how to do that. ---

It looks like the ignition.conf from the 7.9 backup includes some JVM arguments that are no longer valid: ```python STATUS | wrapper | 2024/06/12 15:48:15 | Launching a JVM... INFO | jvm 1 | 2024/06/12 15:48:15 | Unrecognized VM option 'UseConcMarkSweepGC' INFO | jvm 1 | 2024/06/12 15:48:15 | Error: Could not create the Java Virtual Machine. INFO | jvm 1 | 2024/06/12 15:48:15 | Error: A fatal exception has occurred. Program will exit. ERROR | wrapper | 2024/06/12 15:48:15 | JVM exited while loading the application. ``` Post the "Java Additional Parameters" section from your ignition.conf file after the restore. A fresh one for 8.x will look something like this: ```python # Java Additional Parameters wrapper.java.additional.1=-Ddata.dir=data wrapper.java.additional.2=--add-opens=java.base/java.lang=ALL-UNNAMED wrapper.java.additional.3=--add-opens=java.base/java.io=ALL-UNNAMED wrapper.java.additional.4=--add-opens=java.base/java.security.cert=ALL-UNNAMED wrapper.java.additional.5=--add-opens=java.base/java.util=ALL-UNNAMED wrapper.java.additional.6=--add-opens=java.base/jdk.internal.misc=ALL-UNNAMED #wrapper.java.additional.6=-Xdebug #wrapper.java.additional.7=-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=*:8000 ``` ---

Okay, just delete that section and replace it with the one I posted. ---
