Ubuntu – Will there be data loss if I upgrade

upgrade

I am planning to upgrade from 8.10 to 10.04. But I am wondering whether there will be data loss during the upgrade.

For example:

  • Will the applications that I have installed on 8.10 still be there after upgrade?

  • Will the settings of application such as the bookmarks for Firefox and for Google Chrome be preserved?

  • Will all the personal files under my home directory be preserved?

Is there anything else I need to know about upgrading?

Best Answer

  • According to the documentation:

    Renewing the Installation without formating the partitons (in contrast to upgrading), will also keep the personal data and configurations under /home but will renew all system settings under /etc as well as the default set of installed packages.

    However, it is impossible to upgrade from 8.10 directly to 10.04. You would need to upgrade to 9.04, then 9.10, and then finally 10.04. This can be a long and painstaking process, so in your case I would recommend doing a new install over your existing install, which will not format your drive. (More detail here). The installer will preserve the data in your home directory but do an install over the rest of the system.

    As always with every upgrade please make sure you backup your important data.
