Removed the extensive backup and questioning section that was previously here, removed the older releases and troubleshooting sections to place in separate article because it was referencing a lot of unsupported releases. Added a few things to expect with cosmic with the article links. (#1359)

-## When Should I Upgrade?
+## What to Expect
 
-Every release of Pop!\_OS is thoroughly tested and undergoes an extensive quality assurance (QA) process, including the upgrade system itself. In almost all cases, the upgrade from an existing release of Pop!\_OS to a newer release is a smooth transition that takes only an hour or so to complete (depending on download speeds and the speed of the components in the system you are upgrading).
+Pop!_OS 24.04 now includes the COSMIC Desktop. Some changes to expect are outlined in the following articles;
 
-That being said, from time to time, unexpected complications can arise. The likelihood of complications during the upgrade process increases on systems that are:
+- [New keyboard shortcuts](articles/pop-cosmic-keyboard-shortcuts)
+- [New default Applications](/articles/default-apps)
+- [Desktop customization and window behavior](/articles/pop-basics)
 
-- upgrading more than one release at a time
-- running older releases that have already reached the end-of-life period
-- using a large number of third-party software repositories (PPAs)
-
-Before upgrading, it can be helpful to ask yourself the following environment questions:
-
-1. **Do I have a backup of my data (see next section).**
-
-    - YES? - Proceed.
-    - NO? - Make a Backup.
-
-2. **Is this a mission critical machine?**
-
-    - YES? - Wait until upgrading will not stop work.
-    - NO? - Proceed.
+## Upgrade Versus Fresh Installation
 
-3. **Do I have a backup/alternate machine if this one goes down temporarily?**
+A fresh installation is recommended for any release prior to Pop!_OS 22.04. Instructions for a fresh installation can be found [here](articles/install-pop).
 
-    - YES? - Proceed.
-    - NO? - Make a backup, assess your comfort level, proceed if comfortable.
+The likelihood of complications during the upgrade process increases on systems that are:
 
-4. **How recently was this upgrade issued? Have any stability issues been reported?**
-
-    - YES? - Wait a week (or two), check again, then upgrade.
-    - NO? - Proceed.
-
-## Backing Up Your Data
-
-**IMPORTANT NOTE:** The upgrade process will leave your files in place, but no matter which system or version you are running, we **always** recommend first creating a good backup of your files, just to be on the safe side should anything unexpected happen during the upgrade. Internet or power outages can happen to anyone.

-These older Pop!\_OS releases are now unsupported and no new updates are available. After unsupported versions have been removed from the archive and mirror network, you will need to change where your system checks for un-applied updates to be able to upgrade. Open a terminal and follow the next set of instructions to upgrade from Pop!\_OS 18.10, 19.04, or 19.10.
-
-### 1. Get your current system fully updated
-
-```bash
-# change server from us.archive to old-releases
-sudo sed -i 's/us.archive/old-releases/g' /etc/apt/sources.list
-# request release files
-sudo apt update -m
-# configure any packages partially setup
-sudo dpkg --configure -a
-# fix any missing package dependency
-sudo apt install -f
-# upgrade all packages and dependencies to newest in release
-sudo apt full-upgrade
-# make sure the `pop-desktop` meta package is installed
-sudo apt install pop-desktop
-```
-
-### 2. Move any PPA additions out of the way, and get all of the sources pointed at the 20.04 versions
-
-```bash
-# create a backup directory
-sudo mkdir -p /etc/apt/backup
-# move all current PPA entries into backup directory
-sudo mv /etc/apt/sources.list.d/* /etc/apt/backup
-# add the System76 PPA back in
-sudo apt-add-repository -yn ppa:system76/pop
-# change update server back to us.archive.ubuntu.com
-sudo sed -i 's/old-releases/us.archive/g' /etc/apt/sources.list
-# change all release names to focal, the 20.04 release
-sudo sed -Ei 's/cosmic|eoan|disco/focal/g' /etc/apt/sources.list /etc/apt/sources.list.d/*.list
-```
-
-### 3. Now, do the upgrade
-
-This will have a three phases and once the download is complete, you can't change your mind. This works from a new install of 19.04, but some packages may add complications, so make sure you have a backup of important data before moving forward. There may be a question about restarting services, and it is safe to answer "Yes". There may be some questions about using "maintainer" version of configuration files and using the that new version is also very likely what you want to do (and the default answer will work):
-
-```bash
-# get release files
-sudo apt update
-# update the upgrade software first
-sudo apt install dpkg apt
-# upgrade all packages on system to latest release, keeping log in "upgrade.log"
-sudo apt full-upgrade 2>/dev/null | tee ~/upgrade.log
-```
-
-### 4. Now put the PPAs back
-
-You may want to take a look at the files that end in "list" in "/etc/apt/backup" to see if you want to enable them again by moving them back to the /etc/apt/sources.list.d/ directory.
-
-### 5. After the 20.04 Pop upgrade is complete, **Reboot**
-
-### 6. Run the command to upgrade to the newest release
-
-```bash
-pop-upgrade release upgrade
-```
-
-## Troubleshooting
-
-Most upgrades proceed without a hitch, but occasionally things go wrong. If your system hangs on the upgrade process or if it reboots and won't start, then the following steps can help repair your broken OS.
-
-### Stuck Upgrades
-
-If your upgrade appears to hang in place for an extended period of time, click on the `Terminal` item to expand the terminal section. Check what action is available there, then complete the steps to un-hang your upgrade. For help, contact support and we'll be able to provide assistance.
-
-### Broken Upgrade
-
-Pop!_OS has replaced the Ubuntu upgrade tool "do-release-upgrade" in recent releases (21.04 and newer). With updates to the Pop!OS installer, you may find that either using an updated [Recovery Partition](/articles/pop-recovery/) or [Live USB](/articles/pop-live-disk/) with the desired Pop!_OS release using the "Refresh Install" option will be the fastest way to fix your install.
-
-Manually fixing package issues can be hard to diagnose. Use caution when removing system packages. Removing software from PPA's may be required to allow newer packages from the base repositories to install correctly.  Please follow the steps as outlined in this document about [repairing the package manager](/articles/package-manager-pop/) and/or [incomplete upgrades](/articles/pop-incomplete-upgrade/)
-
-Make sure to get the package manager to a fully upgraded status before rebooting your computer.  You should see this line after running all 6 of the [repair package manager](https://support.system76.com/articles/pop-incomplete-upgrade#repair-package-manager-after-failedincomplete-upgrade) commands:
-
-```bash
-0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
-```
+Once restarted, the computer will prompt to login to Pop!_OS 24.04.
