I saw an updated version of EE4 was available. when I did the update a fatal error occurred while doing core data migration. (data migration error) My site is stuck in maintenance mode. I am not sure the best way forward (I’m afraid to reset data) from here without losing any of my event registrations, custom templates etc.

Hi Kerrie,
I’m sorry for the trouble. Do you know what the fatal error was? If it was a fatal error that said that the server is out of memory, you can avoid this by going into wp-config.php and add this line to the Developers section of the wp-config file.
define( 'EE_MIGRATION_STEP_SIZE', 5);
This will make the migration manager migrate only 5 records per request instead of the default 50. That means the migration will go much slower but there’s less chance of a timeout.

It was a server memory issue which has been resolved. I have restored my backup and yet my site is still in full maintenance mode I don’t know the best next step to avoid losing registrations. I reset event espresso capabilities and nothing changed.

Hi Kerrie, was that a WordPress database backup that was restored or was the full site restored?
What is the current version of Event Espresso that is on the site?
Thanks

Kerrie,
Does the maintenance page give you the option to run the migration? If so, you need to run the migration. Once the migration is done it will take the site out of maintenance mode.
