How do I perform an update to EE4 – When i downloaded the zip file – the files inside are not in a folder. EE3 zip file had a folder called event-expresso. Version 4 just has all the files and folders in it – do I just upload these files into the event-expresso folder already in my plugin directory, overwritting the existing files and folders?

Also – Is there a link you can give us for all these (50+) new EE4 features you’re advertising on your site – all I see is EE4 core and EE4 calendar. Thanks

Hi Kevin,

It may help to try downloading the zip file from another browser because some browsers will automatically extract the zip file.

Before updating, I recommend reading this first if you are using any of the Event Espresso 3 add-ons:

https://eventespresso.com/2014/02/event-espresso-4-beta-officially-released/

Along with that, backing up the WordPress database is recommended to allow for reverting to EE3 in case you want to stay with EE3 for the time being. Please note that if you plan on migrating the EE3 data you will need to be sure to have the latest version of Event Espresso 3 up to date before hand.

Here are step by step instructions on how to deactivate EE3 and install Event Espresso 4:

Download EE4 latest version from your user profile page

Go to the Plugins page of your WordPress admin.

Deactivate Event Espresso 3.

Click the “Add New” link at the top of the Plugins page

Click Upload

Click Choose File

Select the .zip file that you have just downloaded

Click the Install Now button

Activate.

A message will display that tells you that Event Espresso is in Maintenance mode. From there it will walk you through the steps to migrate the data from EE3 if you choose to migrate the data or let you start fresh with new data.

Here’s a link with the Event Espresso 4 features:

Hi Kevin,
I have just attempted for a 2nd time to upgrade from EE3 to EE4, both times have been unsuccessful. The first time I went back to EE3 and it was fine.
I noticed that the current update in main mode only shows data conversion from a previous EE4 version. I assumed that this would work with EE3 but maybe not.
Would one of your developers be able to take a look and see if they can work out what’s going on. I wonder if one of the plugins from EE3 has somehow corrupted the database and this is why its not working.

If I attempt to create a new Event, and try to publish, it hangs.
Currently I have no active events.
Thanks

Hi kcray,

Can you try resetting the Event Espresso 4 data from the maintenance tab, then run the migration again?

Before migrating though please check and make sure that all of the Event Espresso 3 add-ons and Event Espresso 3 is up to date with the latest versions.
