NetXMS Support Forum

Hi guys, 
I am getting this error (netxms server uses incompatible version of communication protocol Version 4.5.0). 

I am currently running version 4.5.0 on the server with redhat. I have upgraded the client to version 5.0. 

Can anyone help me to upgrade the server?

dnf update should be sufficient

Thanks, very much.

I mention the step by step that I followed to make it work correctly.

• mysqldump -u root -p --all-databases > all_databases_backup.sql
• dnf update mysql-server
• sudo systemctl restart mysqld

• dnf update netxms-server
• nxdbmgr upgrade
• systemctl restart netxmsd

Right, this is always good practice to have DB backup prior to upgrade. 

In addition, you can also run 
nxdbmgr check
ideally two times - one prior to NetXMS upgrade and the other one after. First run fixed issues, if any, so upgrade runs in a clean way. Second time happens with newer version of nxdbmgr that may have new checks added.
