Converting to Drupal

Want to migrate url_alias of translated content from Drupal7 to Drupal9, any help?..

Hello,

I am trying to import the content from other CMS. The main part of content is article text with images, the article usually contains multiple images.

As part of import (migration) I create new Media entries in process step of migration (see bellow relevant part of migration file)

It's been a few years since I worked with Drupal, but having checked out a Docker container with a demo site, I recall some of things Drupal does really well.  I've got a couple Wordpress sites I'd consider converting to Drupal, but one of the must-haves for me is some sort of security solution like Wordfence.  This plugin was a life-saver for me -- it made security-related problems a thing of the past.  I found some paid options for Drupal (incl, Cloudflare), and I saw Cloudflare has a free tier, but it doens't include a WAF. 

I've dabbled quite a bit with Drupal, somewhere in the Middle Ages. It was fun, it was productive - but sometimes you just take different directions.

I feel like taking 'it' up again. Of course, I'm aware that 'upgrading' from Drupal 5 to Drupal 9 is a definite no-no. Drupal's policy of "upgrading actually means complete re-architecturing" does not seem to have decreased, to the contrary. That's where my question fits in... The idea is not to convert 5 to 9. The idea is to start all over again. Even the data of the 5 era are not important any longer.

Hope all of you are fine.  Actually am not a developer/designer & have not much idea about it. I have a skincare website [spam link redacted] that is currently running on the WordPress platform. I want to migrate the same existing content into the drupal version. Is there any system or converter to convert from WordPress to drupal?

Good day everyone. I'm fed up with spam attacks and other hacking activities with Wordpress, no matter how safe it is. I know drupal is way more secure than that platform. What I wanna ask is, will there be any dramatic drop with my rankings or any serious SEO issues? I can handle slight changes though. Thank you.
