Jump to centos 7 or 8

Post by kbowman » 2019/12/19 19:21:11

I am currently running a custom php software on centos 6. With EOL coming I am looking to update to centos 7 or 8. What could be some possible things that could go wrong with the software that I should be aware of if I were to update

CentOS 6 comes with php 5.3.3
CentOS 7 has 5.4.16 and was released in 2014, EOL 2024
CentOS 8 has a choice of either 7.2 or 7.3, released in 2019, EOL 2029.

To find out the differences you'll need to read the doc on php.net so that you can check if any of the changes affect your code. Or run up a test VM and duplicate your current setup and then test the pants off it. Or better, both.
CentOS 6 will die in November 2020 - migrate sooner rather than later!

Yes, the use of PHP 7.3 is a major factor that probably helps a lot.

SCL for CentOS 7 offers php-5.5. Remi's repo for el7 has php-7.3 and php-7.4.

https://access.redhat.com/support/polic ... life-cycle states:

Code: Select all

AppStream	Release Date	Retirement Date	Release
php 7.3 	Nov 2019 	Nov 2021 	8.1.0
php 7.2 	May 2019 	May 2021 	8.0.0 
The AppStream has shorter life cycle than the BaseOS.

There are php 7.3 copies in both SCL and IUS for el7 though I'm not sure that the list of sclo-php73* packages looks complete (never used them).
