Manage Your Joomla 4 Sites with mySites.guru

This article was written when Joomla 4 first launched. Joomla 4 has since reached end of life. If you're still running Joomla 4, plan your migration to the latest Joomla version sooner rather than later.
Joomla 4 was released on 17 August 2021 after nine years of development. mySites.guru had full support ready from day one.
ℹ️ Full Joomla version support
mySites.guru is compatible with every Joomla version from 1.5.0 onwards - including Joomla 4, 5, and 6. Even if a site has been hacked and compromised, the audit and monitoring tools still work.
How mySites.guru handles Joomla upgrades
mySites.guru never performs major Joomla upgrades automatically. You have to log in and request that mySites.guru perform an upgrade.
When Joomla 3.10.0 was first released, it mistakenly showed a one-click upgrade path to Joomla 4.0.0 in the admin panel. That was never supposed to happen - Joomla 3 to 4 was always a migration, not an upgrade. We blocked the Joomla 3 to 4 upgrade path in mySites.guru entirely to prevent accidental major version jumps.
The Joomla project later acknowledged the issue and moved Joomla 4.0.0 to a separate update stream so that Joomla 3.10.0 sites wouldn’t see it unless the update channel was manually changed.
References:
Joomla 1.5 through 3 all share a single connector plugin. Joomla 4, 5, and 6 each have their own dedicated connector, built to take advantage of the higher PHP requirements in each major version.
Migrating from Joomla 3 to Joomla 4
Migrating to Joomla 4 means checking every template, extension, plugin, and module for compatibility. Joomla’s built-in Pre-Update Checker has a history of reporting incorrect compatibility results, so verify each extension manually.
⚠️ Never migrate on a live site
Perform the Joomla 4 migration on a development copy first. Back up everything before you start, and test your backups.
The dedicated guide covers the mySites.guru side of this in more detail: Migrating to Modern Joomla When Using mySites.guru.
Reconnecting a migrated site to mySites.guru
- Uninstall the mySites.guru system plugin from the Joomla 3 site
- Delete the site from your mySites.guru account
- Perform the mini-migration to Joomla 4
- Use the Add Another Site process to generate the Joomla 4 connector and install it on your migrated site
Joomla 5 and Joomla 6
Joomla 5 and 6 are also fully supported, each with their own dedicated connector plugin. mySites.guru also has tools to check whether your servers are ready for each version:
