I am new to MODX - recently “inherited” several sites running on 2.6.5-pl. Seems to me, some of these have been heavily customized. The original developers are not available, nor is there any documentation.
Some of the sites run on PHP 5.6, which will be shut down very soon, so my first job is to update the PHP version to 7.3, next will be updating to the most recent MODX version.
It looks like 2.6.5-pl core will run just fine on PHP 7.3 ?
If anyone could direct me to best practice of the update procedure - thanks!
I plan on using Akeeba Standalone for backup, which allows me to revert. I do not have SSH access. I am also considering to duplicate the site locally, just in case the Customizations / Extras give me trouble.
