swapping main php version

[ASap]

Hi there,

Currently my server setup is using:

main php: php 5.6 + mod_php
2nd php: 7.4 + fcgi

I'm planning to make php 7.4 as my main php, and swapping the 2nd php with 5.6 + mod_php for supporting legacy php apps.

What are the implication if I swap them?

For example:

a.com using php 5.6
b.com using php 7.4
c.com using php 5.6
d.com using php 7.4

Once I swap the php (by recompiling it) will they automatically swap by themselves? Or, do I need to reconfigure each site? because a.com using php 7.4, b.com using 5.6 as I swap the main php on custom build options?

I'm using DirectAdmin v1.62 on Debian 8.

You need to reconfigure your site

You can also swap the users via a script, to change their "php_select" option to the newly correct version:
