The easiest is to follow the official guide

https://laravel.com/docs/10.x/upgrade#upgrade-10.0

Yeah, I am running latest version of PHP & Composer..

Thank you for your responses.

I will update everything needed in versions on .env and then run 'composer update'

Here goes :

Actions I took:

Copyright (c) The PHP Group

Composer Dependencies

You should update the following dependencies in your application's composer.json file:

• laravel/framework to ^10.0 - # completed
• laravel/sanctum to ^3.2 - # completed
• spatie/laravel-ignition to ^2.0 # added this - it was not present - # completed

Minimum Stability

You should update the minimum-stability setting in your application's composer.json file to stable:

"minimum-stability": "stable", # completed

Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires realrashid/sweet-alert ^4.1 -> satisfiable by realrashid/sweet-alert[v4.1.0].
    - realrashid/sweet-alert v4.1.0 requires laravel/framework ^5.6|^6.0|^7.0|^8.0 -> found laravel/framework[v5.6.0, ..., v5.8.38, v6.0.0, ..., v6.20.44, v7.0.0, ..., v7.30.6, v8.0.0, ..., v8.83.27] but it conflicts with your root composer.json require (^10.0).
  Problem 2
    - mpociot/teamwork[6.1.0, ..., 6.1.1] require php ^7.2.5 -> your php version (8.1.12) does not satisfy that requirement.
    - mpociot/teamwork 6.1.2 requires laravel/framework ^6.0|^7.0|^8.0 -> found laravel/framework[v6.0.0, ..., v6.20.44, v7.0.0, ..., v7.30.6, v8.0.0, ..., v8.83.27] but it conflicts with your root composer.json require (^10.0).       
    - Root composer.json requires mpociot/teamwork ^6.1 -> satisfiable by mpociot/teamwork[6.1.0, 6.1.1, 6.1.2].

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

It would seem easier at this point ( mostly front facing with only backend subscribe and contact request database display ) -- to just move the website over to a new install and then rebuild the admin dash and contact database thing.
