Upgrading Drupal

This question is about updating (not upgrading) Drupal, but I wasn't completely sure in which support forum to ask it. Please direct me to another one if this is not fit.

I have recently installed Drupal 8 according to the official documentation with the following set of commands:

I currently have a Drupal site running 8.9.9..     I have managed to get this far without Symfony.. or any kind of 3rd party software... just using the Drupal front end and managing back end files and database.

Does Drupal 9 absolutely require Symfony or can i still manage it with out it?

Please advise

Hi

We are running Bitnami Drupal on a windows server and we just changed servers. by changing server we have changed server names. our server name used to be Server1:90\drupal to get to drupal. but on the new server with drupal is now Server2\drupal. 

Seems like I have everything working, but when I do a submit on a webform, it fails due to trying to connect to Server1:90.

I have had no luck finding where this link is stored. I dont know if it is in the SQL database?

All the other links seem to be working. 

can anyone help?

I just upgraded from 7.73 to 7.74, and have gotten this warning message several times (which I've never seen before):

Warning: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"? in require_once() (line 341 of /home3/stfranf6/public_html/includes/module.inc).

Is this problematic?  Can I ignore this, or is this a problem with the 7.74 upgrade?

Thanks,

I moved them, and edited composer.json ( as follows:
