patch updates cnmaestro on premises ....

Hi ,

my cnmaestro  ova version is 1.4.0-r11 and package version is 1.5.0-r12 

can i update 1.6.0-r22 in via patch version

no, you have to the same procedure as you did for 1.4.0. release. But first, export data for backup and then later you will be able to import it to the upgraded cnMaestro. It will save you all settings and statistics for all devices.
