Hi
I would like to know the best practice for migration , from 20.1 to 21.1?
In place upgrade 20.1 --> 20.7 --> 21.1 or backup configuration from 20.1 and make new install 21.1 and restore backup configuration.
Thanks for your answer.
20.7 saw a major shift in the underlying OS iirc. I would backup, install fresh with config.xml imported...
