Re: [PHP] upgrading to 7.4.2

I am copying this back to the admin list to keep the discussion where more
people can comment. (The admin list is more appropiate than the PHP
list where your initial questions were posted.)

If you have rpms for 7.4.2 you can do the update that way. That just replaces
the binaries, it doesn't do anything to the data. That technique will
work as long as you are doing an upgrade between two minor releases of
the same major release. You have to do a dump first if you are changing
major release version. Also you should read the release notes for 7.4.2
as there are some special instructions in this case.
