PHP version - Upgrading from SMF 2.0.18 from 1.1.21

I want to update my SMF install from version 1.1.21 (running on php 5.3) to version 2.

Do I run upgrade.php with PHP 5.3 or should I switch to php 7.x before running upgrade? Or should I do something else? Like switch to 5.6?


5.4 would be the safest for 2.0.18

After that you can bump PHP all the way up to 7.4

if you have lots of mods then 7.2 and onwards may present a few minor issues for you.

I used PHP 5.6 and had no hassles and then moved to PHP 7.3 (Centos6 highest possible PHP level).

I also run a test system with PHP 7.4.
The configuration of my Linux VPS (SMF 2.0 with 160+ mods & some assorted manual tweaks) can be found here and notes on my mods can be found here (warning: those links will take you to a drug related forum). My (House) music DJ dedication page is here


Note you lose all mods & themes on a major upgrade, e.g., from 1.1.x to 2.0.x.

I'd go right to 7.4.
Address the process rather than the outcome.  Then, the outcome becomes more likely.   - Fripp
