Unable to migrate to latest version i.e. 4.10. (2)

I am again opening this ticket as I am facing difficulties in migration to the current version. Actually, we have near about 16000 events and migration stops after 86%. We have tried your suggestions but that doesn’t work.

The two suggestions which I have tried are:

1) define( ‘EE_MIGRATION_STEP_SIZE’, 20);
2) deactivating all modules.

Just for FYI – We are able to successfully able to migrate on staging but it is only possible when we delete all events.

Please help me in that so that we can succesfully migrate the event espresso on production.

May I ask what kind of server is your site running on? (shared, VPS, dedicated) It sounds like the database query is timing out (due to having 16000 events).

We’d like to help you with this, could you reply if you have a moment?

In addition to the above, maybe you could download and install this branch of EE4.10 on your staging site.

This is a shot in the dark, but could help if your server’s database is locking up when the migration script runs.
