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.

For an exchange and office365 migration , i need to open from lan to the unbelievable url and ip list from Microsoft.
