RHEL9 upgrade and the licensing software - recommendation for existing setups

In any case using a emergency standby license server is advised to ease the process of upgrading the setup. Please be reminded, that an emergency server is mandatory for any FNE/X related setup. 
 
 For upgrading from RHEL7 to RHEL9 and how to handle the licensing software on single/standalone FNE server:  
 1. uninstall licensing software while OS is still RHEL7 

 1.1 With release 2023.11.0.0-23324 and newer use: 
 sudo sh install-fne-<year> uninstall 
 

 1.2 For older releases find the installed packages ( rpms ) with fne-status command under Installed components 

 1.3 Use the list entries with: (example) 
 sudo yum remove advantest-fne-server advantest-fne-server-viewer 
 2. update OS to RHEL9 3. download and install latest FNE software 
 sudo sh install-fne-2024.01.0.0-24043-rhel9.sh server 
 for a proxy setup use  fnx instead of server 
 This would obviously mean some downtime if there is no failover/backup or emergency standby server in place. An emergency server is mandatory and set up will prevent any downtime. 
 
 
  For upgrading from RHEL 7 to RHEL 9 and how to handle the licensing software with a failover setup and triad setup: 
 Failover setup must be in place beforehand! It cannot be added afterwards without a completely new setup including the registration for the back office.  
 On Primary server: 1. uninstall licensing software while OS is still RHEL7 

 1.1 With release 2023.11.0.0-23324 and newer use: 
 sudo sh install-fne-<year> uninstall 
 

 1.2 For older releases find the installed packages ( rpms ) with fne-status command under Installed components 

 1.3 Use the list entries with: (example) 
 sudo yum remove advantest-fne-server advantest-fne-server-viewer 
 2. update OS to RHEL9 3. download and install latest FNE software 
 sudo sh install-fne-2024.01.0.0-24043-rhel9.sh server 
 for a proxy setup use  fnx  instead of  server 4. run as normal user 
 fne-failover-setup repair primary <failover host> 
 During primary downtime the clients will switch to the failover. Once the primary is finished upgrading and has a running licensing software, clients will automatically reconnect to primary within 2-20mins. 
 On Failover server: 1. uninstall licensing software while OS is still RHEL7 

 1.1 With release 2023.11.0.0-23324 and newer use: 
 sudo sh install-fne-<year> uninstall 
 

 1.2 For older releases find the installed packages (rpm's) with fne-status command under Installed components 

 1.3 Use the list entries with: (example) 
 sudo yum remove advantest-fne-server advantest-fne-server-viewer 
 2. update OS to RHEL9 3. download and install latest FNE software 
 sudo sh install-fne-2024.01.0.0-24043-rhel9.sh server 
 for a proxy setup use  fnx  instead of  server 4. run on primary as normal user! 
 fne-failover-setup repair failover <failover host> 
 HostIDs of primary and failover servers must not be changed! 
 On Tertiary server: 
 1. uninstall licensing software while OS is still RHEL7 

 1.1 With release 2023.11.0.0-23324 and newer use: 
 sudo sh install-fne-<year> uninstall 
 

 1.2 For older releases find the installed packages (rpms) 
 rpm -qa | grep fne-proxy 
 

 1.3 Use the list entries with this command: (example) 
 sudo yum remove advantest-fne-proxy advantest-fne-proxy-base advantest-fne-proxy-features 
 2. update OS to RHEL9 3. download and install latest FNE software 
 sudo sh install-fne-2024.01.0.0-24043-rhel9.sh tertiary 
 Afterwards the proxy setup can be run on primary: 
 /opt/flexlm/bin/fne-proxy-setup <secondary> <tertiary>
