Proposal for extra information to add in the wiki and/or in the manuals ?
Contents
Presentation
This page deals with the different ways to upgrade a Mageia operating system version from n to n+1. It is different from a simple packages update. It is not possible to upgrade from more than one step.
Requirements
To be able to choose the right upgrade method, you may need to know one or several following features about your existing system:
- If it has or hasn't a separate /home partition
- Its architecture, 32 or 64 bit
- Its firmware mode, bios or UEFI
- The disks partitioning mode, ms-dos (also called MBR) or GPT.
- The installed desktop(s) environment
- The user-names with their UIDs and GIDs
- The used boot loader
You also need to know which of theses features you want to change in the new system if any.
At last, whatever your decision is, always
- read the errata, there is a wiki page for each release,
- backup your data
- update your Mageia version n
Vocabulary
We are used to name the different upgrades according to what partitions are formatted as shown in the following table, but take care that other names may be used in other pages.
Situation | No formatted partition | only / is formatted | / and /home are formatted |
---|---|---|---|
Name | Simple upgrade | Clean install | New install |
If one or more other OS(es) are able to be loaded on your system, we call that "dual boot" if there is two OSes and "multi boot" for more, often simplified by "dual boot" whatever their number is. e.g.: A clean installation in dual boot.
Note: You can't do a clean install if you don't have a separate /home partition |
Media choice
Media possibilities
You need to choose you media according to the upgrade you plan to do.
Media | Simple upgrade | Clean installation | New installation |
---|---|---|---|
Live | no | yes | yes |
Classical | yes | yes | yes |
CLI (changing the repositories) | yes | no | no |
Note: Netinstall.iso is not really a media by itself but a way to boot and then load a media that is present locally or via a network. |
Advantages, drawbacks and special features
- Simple upgrade
- Advantages: Quick (no afterwards configuration), easy (no questions from the installer)
- Drawbacks: If problems, instabilities, useless data, ... exist, they are kept. Some upgrades can be risky when the step is important (e.g. KDE4 > Plasma5)
- Special features:
- In case of important graphic evolutions (e.g. KDE4 -> Plasma5) it is more secure to do the upgrade in text mode. See the Howto below.
- It is impossible to change any of the characteristics listed above
- Third party applications are not updated
- Boot loader configuration is updated, may need manual action in dual boot
- When the installer ask you to choose between "Upgrade" or "Installation", you choose "Upgrade".
Note: If you want to change the architecture from 32 bit to 64 bit, an upgrade is not possible as / must be formated |
- Clean installation
- Advantages: Clean the system (see Simple upgrade drawbacks), few configuration (icons, widgets, wallpapers, bookmarks, data ... are preserved), low risk of failure.
- Drawbacks: Need some skills (to choose the partitions and the desktop, to create the users, ...). Some configuration to do again (e.g. networks, some devices not fully supported)
- Special features:
- Take care the installation preserves the same users UIDs and GIDs. See the Howto below.
- Third party applications are not updated
- Allow to move from 32 bit architecture to 64 bit one and vice versa
- Boot loader configuration is updated, may need manual action in dual boot
- When the installer ask you to choose between "Upgrade" or "Installation", you choose "Installation".
- New installation
- Advantages: Everything is clean, /home included,
- Drawbacks: need skills and is longer, it is like a first installation, the whole configuration must be re-done.
- Special features:
- It is an opportunity to update the disc partitioning,
- If no dual boot, it is also an opportunity to move from bios to UEFI mode
- Boot loader configuration is updated, may need manual action in dual boot
- When the installer ask you to choose between "Upgrade" or "Installation", you choose "Installation".
Note: If you want to change a msdos disc to GPT, only a new installation allow that as a new disc partitioning is needed. |
- Whatever in dual boot
- Advantages: Add the possibility to use two or more OSes on the same computer and if wanted, to share the data,
- Drawbacks: The boot loader is rewritten and skills are needed to re-configure it if necessary.
- Special features:
- If you don't want the Mageia boot loader to be installed by default, take care during the installation to act in order to keep your favourite boot loader (see the Installer manual).

Howto do a simple upgrade in text mode
After having started and updated your system:
Open a console and enter the root mode | |
Stop the graphic interface | Template:Root console |
Delete the current repositories | Template:Root console |
Add the new repositories | Template:Root console |
Test the upgrade, all the packages are downloaded and the upgrade simulated | Template:Root console |
If the test is OK, start the upgrade | Template:Root console |
When it is over, reboot the system | Template:Root console |
