 CloudLinux 7 to 8 conversion tool
 
 ## Introduction
-This script is the official tool for converting a CloudLinux 7 server with Plesk to CloudLinux 8. It uses the [AlmaLinux ELevate tool](https://wiki.almalinux.org/elevate/ELevate-quickstart-guide.html), which is based on the [leapp modernization framework](https://leapp.readthedocs.io/en/latest/). The script includes additional repository and configuration support provided by Plesk.

 ### Conversion stage options
-The conversion process consists of three stage options: "start", and "finish". To run stages individually, use the "--start", and "--finish" flags, or the "-s" flag with name of the stage you want to run.
+The conversion process consists of two stage options: "start", and "finish". To run stages individually, use the "--start", and "--finish" flags, or the "-s" flag with name of the stage you want to run.
 1. The "start" stage installs and configures ELevate, disables Plesk services and runs ELevate. It then stops Plesk services and reboots the server.
-2. The "finish" stage must be called on the first boot of CloudLinux 8. You can rerun this stage if something goes wrong during the first boot to ensure that the problem is fixed and Plesk is ready to use.

 ### Leapp unable to handle packages
 Leapp may not be able to handle certain installed packages, especially those installed from custom repositories. In this case, the cloudlinux7to8 will fail while running leapp preupgrade or leapp upgrade. The easiest way to fix this issue is to remove the package(s), and then reinstall them once the conversion is complete.
 
+### Leapp cannot choose which package to install
+This issue may occur if unsupported repositories are used. For instance, if an unexpected EPEL repository is enabled on the server, the cloudlinux7to8 process will fail when running `leapp preupgrade` or `leapp upgrade`. This is due to conflicting packages between the el8 and el7 repositories. The simplest way to resolve this issue is to switch to the standard repositories.

 ### Temporary OS distribution hangs
-This issue may occur, for example, if there is a custom python installation on the server. The conversion process will fail while upgrading the temporary OS distribution, and the temporary OS will hang with no notification. To identify the issue, connect to the server using a serial port console and check the status of the conversion process. To fix the issue, reboot the server. Note that an unfinished installation process may result in missing packages and other issues.
