<![CDATA[netxms server uses incompatible version of communication protocol Version 4.5.0]]>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?

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.

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

  1. mysqldump -u root -p --all-databases > all_databases_backup.sql

  2. dnf update mysql-server

  3. sudo systemctl restart mysqld

  4. dnf update netxms-server

  5. nxdbmgr upgrade

  6. systemctl restart netxmsd
