Update Stretch top buster

[mru73]

Hi there. currently using domoticz v4.10717 on stretch and would like to update to Buster with the latest stable domoticz version. I need step-by-step instructions to use the existing database from domoticz. I don't want to create new devices and I'm a beginner, thank you
