Upgrading Drupal

So I lost my old drupal6 site when my hardware broke. Fortunately I have a back up of the drupal directory on the root server and the database. 

I guess I just need to know what is the correct method of getting my site up and running again. Is it possible to import the database directly into the latest drupal version or do I have to install drupal6 again?

Thanks for any help.

I'm a Drupal novice and have been playing around with it for the last few months. It seems like every 'how-to' article tells you a different way and a reason not to do it the other way.

I am a sysadmin for some developers and don't plan on getting too far in over my head but want to successfully support Drupal with Core and Module updates as needed for security.

I set up some Drupal instances on a test vm and have some questions here with my guesses on the answers and would appreciate confirmation and perhaps a little guidance.

I am trying to update my drupal 8.6.15 site with composer update. And it does not work appropriately

My composer.json file:

I administer a Windows Server running IIS with Drupal 8. I have some web developers who are doing the actual site development. They are the ones installing and using Modules, and they do this via the web interface. Note that I installed Drupal 'recommended-project' using Composer and have been updating it with Composer.

Would it make sense to keep the Modules out of the composer.json file and just continue to let the devs manage them manually themselves, and only use Composer to update Core?

In order to upgrade to 9.0.5 from 8.9.5, I had to uninstall some modules that composer did not like for some reason: front, module_filter,  uptime_widget. These all have D9 versions, and I edited composer.json to specify them. I uninstalled all these modules using the extend/uninstall menu in D8 before the upgrade.

But then, after D9 was (mostly) working, I reinstalled them:

Hi,

I have to upgrade the core of a Drupal7 site from 7.69 to 7.72.

Usually I update Drupal using drush:

drush up drupal

On this server drush runs without errors:
