Hi,
I’m trying to upgrade my EE install from 3.1.37.8.P to 5.0.19.p. After deactivating the old plugin, and activating the new one, the migration UI appeared, but only copied across one event (‘Test Event 1’), and no attendee data. How do I move the data over to the new tables?
Thanks!

Hi There,
You can follow the migration process here to migrate from EE3 to EE5: https://eventespresso.com/wiki/how-to-upgrade-event-espresso/#update-event-espresso-4
Hope that helps.

Sam, thanks for your swift response, but reading the documentation was the first thing that I did. If you take another look at my message, you’ll find that I followed the instructions in your link already (the steps under the heading “Complete the Migration”) but having completed the steps, EE5 only has one event called ‘Test Event 1’, whereas if I disable EE5 and re-enable EE3, all of my actual events are still there.
I tried dropping all the new wp_esp_ tables and starting again, to the same effect. My existing EE3 data is in wp_events_ tables in the DB. Do you have any more helpful suggestions?

Hmmm. I think the only way to find that out would be to read my first message again, Sam.

Sorry for the confusion above.
Can you please reset EE4 again and click to activate it once again, can you add a screenshot of the next page you see on that page here, please?

Make sure to keep a database backup before migration.
Looking forward to helping you.

Hi there,
Have you previously installed ee4 to test it out before?
It sounds like the EE4 -> EE5 migration may have triggered, which will happen if you’ve previously installed EE4.
We can walk through resetting EE4/5 to retrigger the migrations if that’s the case.

Thank you. This sounds likely. How can I reset to a pre-EE4/5 state?

Backup your database before moving forward (these steps drop tables, if something goes wrong the only way you’ll be able to get that data back is if you have a backup, so please don’t skip backing up).
Activate the latest version of EE4/5 you have installed.
Go to Dashboard -> Event Espresso -> Maintenance -> Reset/Delete Data.
Hit the ‘Permanently Delete ALL Event Espresso Data’.
EE will wipe all related EE4+ data and deactivate.
Re-acitvate it again and it should trigger the EE3 migrations.

Well, that didn’t go very well:
“Data Migration Error
Your last Database Update had a fatal error and was halted.
Internal Server Error”
I used the form on the page this message was shown to send in the crash report.

Tragically, activating that version of EE4 causes the fatal “critical error on this website” error. I’m running PHP 8.3, I’m able to downgrade to 8.1 at the earliest. Would that help?

I need to know what the fatal is to be able to answer.
Do you have the full error? It will usually be saved in the server’s PHP error logs.

Hi there,
Rather than me chippin away at individual errors, do you mind if I clone the site so I can see all of the errors being thrown and get a fix for the migration?
I can then send you a patch copy of EE5 with any changes required so you can run the migration yourself.
To do the above I usually use UpDraft and create a backup, download it locally and and install, then work through the issues being thrown. If that’s ok just send temp login details for the site over using this form:
https://eventespresso.com/send-login-details/
I’ll get a patch ready for you asap.
