We have EE 2.3.1 installed with about 5 extra sites adding up to 8 sites. Looking at the directions for updating from 2.3.1 to 2.4, it’s not clear to me if I need to also replace each site’s individual index.php file.

3. Restore Modified Files
Files and settings that are specific to your site should now be restored from the backup you made in Step 1.
Restore any modifications made to the following files, such as updating the system folder name or path:
admin.php
index.phpIf you are using the Multiple Site Manager, the same should be done for each MSM site’s index.php and/or admin.php file.
I’ve updated the main admin.php and index.php file but don’t know if I then need to copy the same new index.php file into each site’s directory replacing what’s already there.
If so, what odd behavior might we see if we don’t? Has the index.php file changed at all between these versions?
