I have installation of Omada Controller version 5.14.20.9. I am trying to stand up a new server and restore a backup of the existing server to the new server. The Omada Controller isntallation is on the same 5.14.20.9 version. When attempting the restore, I get an error in the UI and the restore fails. How can I restore the backup from one server to a new server? 

 

Error in the UI

 

Restore failed

Failed to restore because of unexpected errors. Please try again later.

 

Error in the server.log file: I get an error in the server log file regarding the restore but the forum won't let me include the details in the post.

I'm trying to run on a fresh Windows server installation. 

 

I got it working - issue was the java version. 

 

Thanks for your help.

Hi  @jonmaxey 

 

Is the backup file also from controller v5.14? or from a lower version?

Yes the backup file is from the same controller version. This is the error in the log java.lang.reflect.InaccessibleObjectException: Unable to make field private static final long java.util.LinkedHashMap.serialVersionUID accessible: module java.base does not "opens java.util" to unnamed module @77888435 For some reason I'm prevented from posting the full stack trace from the log.

Try reinstall Java and make sure you use 64bit

Yes I'm using 64bit java. I've reinstalled java. Is there a specific java version required for the controller?

Java 8 i required

 

what are you running your controller on? Windows, Linux docker or clean installation.

 

a new version of Omada has arrived, you can try upgrading to v5.14.26.1, maybe it works better., I tested restore on this myself and it worked well
