\** - upgrading to Oracle Linux 9 is available with the [Oracle Leapp utility](https://blogs.oracle.com/linux/post/upgrade-oracle-linux-8-to-oracle-linux-9-using-leapp) and will not be supported by ELevate project.

**Requirements:** You need CentOS 7, AlmaLinux 8, EuroLinux 8 or Rocky Linux 8 system installed to use this guide.
### Requirements

* A fully updated system is required to accomplish the upgrade. So, install the latest updates first, and reboot.
You need CentOS 7, Scientific Linux 7, AlmaLinux 8, CentOS Stream 8, EuroLinux 8 or Rocky Linux 8 system installed to use this guide.
**NOTE:** Since the CentOS 7 repositories are now offline you will need to swap to the CentOS vault, or you can use our CentOS 7 mirror that we've setup for use with ELevate:
```
sudo curl -o /etc/yum.repos.d/CentOS-Base.repo https://el7.repo.almalinux.org/centos/CentOS-Base.repo
```

## Upgrade steps

* A fully updated system is required to accomplish the upgrade. Install the latest updates and reboot your machine:
```
sudo yum update -y
sudo reboot
```
**NOTE:** Since the CentOS 7 repositories are now offline you will need to swap to the CentOS vault, or you can use our CentOS 7 mirror that we've setup for use with ELevate:
```bash
sudo curl -o /etc/yum.repos.d/CentOS-Base.repo https://el7.repo.almalinux.org/centos/CentOS-Base.repo
sudo yum upgrade -y
sudo reboot
```

* Install `elevate-release` package with the project repo and GPG key.
```
sudo yum install -y http://repo.almalinux.org/elevate/elevate-release-latest-el$(rpm --eval %rhel).noarch.rpm
```
```
sudo yum install -y http://repo.almalinux.org/elevate/elevate-release-latest-el$(rpm --eval %rhel).noarch.rpm
```

* Install leapp packages and upgrade data for the OS you want to upgrade. Possible options are:
* leapp-data-almalinux
* leapp-data-centos
* leapp-data-eurolinux
* leapp-data-oraclelinux
* leapp-data-rocky
```
sudo yum install -y leapp-upgrade leapp-data-almalinux
```

```
sudo yum install -y leapp-upgrade leapp-data-almalinux
```

* Start a preupgrade check. In the meanwhile, the Leapp utility creates a special */var/log/leapp/leapp-report.txt* file that contains possible problems and recommended solutions. No rpm packages will be installed at this phase.

:::warning
Preupgrade check will fail as the default install doesn't meet all requirements for upgrade.
