|---|---|---|---|
| 1 | Upgrading an XWiki instance brings it to a newer version, so that it benefits from the latest features and stops being exposed to the security issues fixed since. | ||
| 2 | |||
| 3 | Before starting: | ||
| 4 | |||
| 5 | * [[Back up your data>>xwiki:Documentation.AdminGuide.Backup]], so that the instance can be restored if the upgrade goes wrong. | ||
| 6 | * [[Update the installed extensions>>extensions:Extension.Extension Manager Application||anchor="HUpgrade"]], because a newer version of an extension often carries the compatibility fix the new XWiki version needs. | ||
| 7 | * Read the [[Release Notes>>xwiki:ReleaseNotes.WebHome]] of every version between the one you are running and the one you are upgrading to, in particular the sections named {{code language="none"}}"Issues specific to XWiki <version>"{{/code}} and any change to the [[prerequisites>>documentation.xs.admin.installation.prerequisites.WebHome]]. | ||
| 8 | |||
| 9 | An upgrade then has two parts, in this order: | ||
| 10 | |||
| 11 | * [[Upgrading the distribution>>documentation.xs.admin.upgrade.distribution.WebHome]] — the XWiki software on the server, replaced from the filesystem or through the package manager. | ||
| 12 | * [[Upgrading the flavor>>documentation.xs.admin.upgrade.flavor.WebHome]] — the wiki Pages, updated from a browser. |
