WLC Upgrade

Hi,

we have two WLCs in HA mode (8540 model), we're planning to upgrade them to latest version 8.10, so please your kind advice for below queries:

1- is the version 8.10 stable? and can I upgrade directly from 8.5?

2- during upgrade activity, is the APs will take the new software directly or I need to upgrade them in advance?

3- any recommendations for best practice.

thanks in advance.
