Upgrade Joomla 2.5 to 3.x

Question

Trying to upgrade Joomla 2.5.14 to latest Joomla 3.x. Have a backup and already setup "Short Term Support STS". Made sure allow_url_fopen = on and allow_url_include= off. But still not getting the update. Says I already have the latest version. Anyone have any ideas on this issue?

Thanks!

OK, so resolved issue. Using STS was no good, going to extension upload was no good, so went the classic way of uploading Joomla 3 stable package zip to replace Joomla 2.5 files. But before doing that, I disabled every non-core Joomla plugin and set a default Joomla template before dropping the upgrade files. After that, the dashboard was looking messed up, so went to Extensions manager > Manage > and used "Discover" + "Database". Changed the admin template to a Joomla 3 template. And now everything seems to be back to normal, but there seems a long way to updating plugins/components. STS and extension upload to upgrade is still not working.. so I guess I'm stuck with manual upgrade.

Answer 1

If you don't see latest available version, Go to:

• Extensions>Extension Manager>Update Tab
• Purge Cache
• Extensions>Extension Manager>Discover Tab
• Purge cache
• Extensions>Extension Manager>Database Tab
• If Errors in DB, Click the 'Fix' button

Go back to Components>Joomla Update Set Options>Update Server to STS

You should be able to see latest version now.

Also, before upgrading, go to Extensions>Extension Manager>Warnings and check there aren't any alerts

Answer 2

Try the button "Purge cache", clear your browser’s cache, and check again for an update. Having said that, it is discouraged to do so in most cases:

you should not upgrade from Joomla 2.5 to Joomla 3.x unless you are certain that all of your additionally installed extensions (from third party developers), especially templates, are Joomla 3.x ready or have a Joomla 3.x version that you can upgrade to.
