Hi,  
I am running Mautic 2.15.1 on Ubuntu, and want to upgrade to the latest release. I saw in the upgrade instructions that one prerequisite is running Mautic 2.16.3.  
What should I do to do the upgrade? Should I first upgrade from 2.15 to 2.16.3?

Yh, upgrade to 2.16.3 first. Then update the schema I.e [yourmauticurl.com/s/update/schema](http://yourmauticurl.com/s/update/schema) (just to be safe for further upgrades), then move on.

Yes, like @devsrealm says, you’ll have to update to 2.16.3 first. The schema updates that @devsrealm mentioned will be applied automatically when you update 😊

Mautic will automatically offer you the correct version, so if you’re on \<2.16.3, it will first offer to update to 2.16.5 (released yesterday), when that’s done, you’ll be prompted to upgrade to Mautic 3.

**MAKE SURE YOU HAVE A BACKUP BEFORE UPDATING!**

There are two ways to do this:

**UI (User Interface) upgrade**

You should see a notification pop up in the Mautic interface under the notification bell (top left corner). If you click on it, you should be able to start the upgrade process.

**CLI (Command-Line Interface) upgrade**

- Go into your Mautic folder (e.g. `cd /var/www/html`)
- (if you’re on Mautic 2) run `php app/console mautic:update:find` and follow the steps
- (if you’re on Mautic 3) run `php bin/console mautic:update:find` and follow the steps
