  - Before updating, don’t forget to update the installation script (see the Installation section). Use the installation script for upgrades.
  - After updating, verify that the receivers have started (check with `netstat -nlpa | grep 1500` and `netstat -nlpa | grep 1501`). The sockets should be listening on ipfixreceiver2.
  - If receivers did not start, run the script: `sudo sh /var/qoestor/backend/qoestor-config.sh`
