Hello,
After updating to 4.6 and then moving to production in WPEngine my site is down with a HTTP 500 error. I see the following in the logs:
PHP Fatal error: Cannot redeclare class ee_data_migration_class_base in /nas/wp/www/cluster-103/megadoevents/wp-content/plugins/event-espresso-core-reg/core/EE_Data_Migration_Script_Base.core.php on line 636
I need to investigate more, and I do realize that the WPENgine publish process is a bit of a black box. That being said, this scenario has always worked for me before and I expect quite a few folks to use WPEngine and possibly hit this.
Any clues?

Hi,
Please login to your site using an SFTP client and then rename the Event Espresso plugin folder.
event-espresso-core-reg –> event-espresso-core-reg1
That should restore access to your site. Then go ahead and login to your WP-admin.
From here, restore the name of the plugin folder:
event-espresso-core-reg1 –> event-espresso-core-reg
Then try reactivating Event Espresso through your WP dashboard.

Thanks for the response, yes, this allows me to get back in, of course. However as soon as I rename the folder back, the error occurs again…

Okay, the bug is with WPEngine. Basically the staging to migration process does not mirror the file system correctly – in other words, it ADDS new files but does not DELETE files that were deleted from the staging environment. It looks like you guys have deleted a few PHP files and refactored – WPEngine ignored that, so I had duplicate classes.
Thank you!!

Thanks for clarifying. You are correct on the major release.
An update will not work correctly if files are merged (overwritten).
Enjoy your weekend!
