Upgrade EVE-ng Community edition to EVE-ng professional

 Mandatory pre-requisites:

  • Internet must be reachable from your PC and Vmware
  • DNS must work properly and name resolution happening correctly
  • Enough Hard disk space should be available
  • Root partition should have atleast 10GB free space and boot partition must be 50MB

 Note: Take backup of all labs especially if customized templates and settings are used.

cd /opt/unetlab ;  tar -czvf /root/labs-backup.tgz labs

 

Update steps:

Step 1: Free / clear older packages from EVE

apt autoremove

Step 2: ensure to have free space on EVE Hard disk, to verify same issue command vg-root and /boot should not be 100% or close to it.

Df-h

Step 3: verify named based ping. e.g. www.yahoo.com if you get ping response it is ok to proceed else check DNS IP assignment for EVE

Step 4: execute command

Apt update

And when it prompts to confirm, answer “Y”

When installation proceeds it may ask few more inputs related to configuration. Reply “N” for below as you are upgrading to newer version and it is asking to keep your current version.

Keep local version currently installed and Press “Y” to confirm

After installation is successfully complete reboot the EVE.

 

Downgrade EVE-ng

 To rollback EVE-ng professional edition to EVE community issue the below commands from CLI of EVE.

  • Echo “drop database guacdb;” | mysql -u root –password=eve-ng mysql
  • apt update
  • apt install eve-ng-guacamole
  • apt install –reinstall eve-ng-guacamole
  • apt install eve-ng
  • Systemctl disable docker
  • Systemctl disable docker.service
  • Systemctl stop docker.service
  • Systemctl disable udhcpd

 

Next Step: reboot EVE

reboot

When you reboot you will get a warning that all your multi configuration sets for labs will be lost and only initial configuration will be retained so backup all devices configuration before proceeding with rollback
