Hi,
I am going to upgrade mybb1806 to mybb1822 with PHP 7.1

Experts and Experienced members, advice me regarding what to do for a safe upgrade?
I see its documentation to upgrade but clear opinions will help much more.
Which precautions to be taken before upgrade?

Please guide.
Thank you.

Please refer to this documentation on upgrade https://docs.mybb.com/1.8/install/upgrade/

Generally speaking, there are three things before upgrade you'd better to check/do:

• database backup
  
• webroot backup
  
• disable plugins
  

1.......Before upgrade from 1806 to 1822 , If I had created 3 subdomains, than should i delete all three subdomains ?
Is there any problem and effect on upgrade if main domain and all subdomain having different PHP configuration?
I kept main domain on PHP 7.1 and other subdomains on 7.0, 7.1, 7.3.


2... Should I delete all themes except default before upgrade?

3.... How to what I am using, check Apache 2.2, Apache 2.4 or Nginx for putting restrictive code???........I have Linux server hosting. and SSL certificate installed form letsencrypt.
In my panel...in Apache handler show below details.
