Upgrading Drupal

Hi!

What is the recommended way to update Drupal9?

# Folders and files:
/config
/files
/helpers
/vendor
/web
composer.json
composer.lock
docker-compose.override.yml
phpunit.xml

* Modify composer.json (composer.lock?) with drupal version:

Hello, a web agency has built us a website using Drupal, they specifically told us NOT to update it ourselves and instead, only they could do this. As far as im aware, the site has not been backed up since it was launched in December 2020. Every time I go into the back end to make changes, im told by Drupal that it needs updating. We are currently on Drupal version 8.

We are about to switch over to a new agency to look after the site but they have told us the following:

Hi ,

I have a D8 site with about 1000 nodes with its content published. I am developing a new D9 site with a fresh database as per its requirement ( not the method of upgrading the existing site as it requires many feature modifications , additions & optimizations ).

Could I get a suggestion for the best way to recreate the pages with its content in D9 ? Do we have to do that manually only or are there any quick methods to accomplish this ?

Thanks

Hi,

I am working on drupal 8 to 9 upgrade.

I am using tealiumiq contributed module (https://www.drupal.org/project/tealiumiq/), this module is not compatible with Drupal 9 version.

There is a patch https://www.drupal.org/files/issues/2021-03-08/d9_compatibility-3202186-... available to resolve this issue.

I have a neglected out of date site with lots of content. It's drupal core 5.7 and I would like to upgrade it to at least Drupal 7, maybe Drupal 8. Most of the modules used are not supported.

What is the best way of going about upgrading this site?

Thank you for your help.

Tam

I have a fully functioning Drupal site (Varbase), but when copy it to production environment I get circular reference error.
