Advice Sought for the Bare Minimum Number of Backup Items

  • I'm seeking advice for a long-delayed update of Opera.

    I intend to wipe everything, including my profile except for the bare essentials because of some issues when downgrading after a pretty disastrous upgrade, where I received a warning about the profile being for the version of Opera that I was downgrading from.

    I've up- and downgraded and parallel-installed multiple versions of Opera quite a few times over the years, never changing my profile folder and never getting a warning about the version of my profile, which I thought was intentionally designed to be invariant across Opera versions.

    Backing up my history and bookmarks seems pretty straightfoward, but backing up my extensions (especially to preserve the data in my V7 Notes extension) looks a little more complicated. Looking at

    Opera help: Crashes and issues

    I need to back up

    Extension Cookies: Cookies associated with your installed extensions, such as location data for a weather extension

    Extension Rules: A storage area for your extensions’ rules that need to be persisted

    Extension State: A storage area for your extension’s states that need to be persisted

    Extensions: Your installed extensions

    Local Extension Settings: A storage area where your installed extensions can store local data

    Please let me know if this is all I need to preserve my extensions' data.

    Thanks
