Following the instructions from here, I'm trying to upgrade my Drupal 7 site to Drupal 9. It went reasonably smooth, but now I'm confused:In the upgrade review I see that
52 Modules will not be upgraded
Following the instructions, I installed and activated a large part of those 52 modules, so I'd have expected that those modules would be available for the upgrade. For example the report lists:
need to renew some my old sites made by drupal. Some on 7.x version some on 8.4 version. All are for present and promote services and product B2B, like machines and so ....
Salsa Digital had an existing bank of support clients who required application support, security patching and adhoc feature enhancements. To formalise our support structure and meet growing demand, we created the Salsa Digital Service Desk. More about Salsa Digital support
I'm dealing with an older site that is still running Drupal 7.59 with PHP 5.6 and it would need to be upgraded to Drupal 7.99 and work with PHP 8.0 at least. I'm pretty inexperienced with Drupal in general, is it simply a matter of replacing the files in the server with the Drupal 7.99 ones and executing update.php or is there more to it?
