I have upgraded from 3.1.27.1 to 4.2.5 now there are no events listed.
I have followed the advice in this post without success…I can’t seem to trigger the data migration utility.
After looking around in the core I can see that there are scripts meant to convert DBs between 3.1.26 and 4.0.0 to 4.1.0, and, between 4.1.x to 4.2.0.
Is there anyway to way to force the migration script?
How can I solve this problem?
My WP version is 3.9.1
Thanks

Hi,
After deactivating 3.1.27 and activating EE4 did a “What’s new” screen pop up?
Going to the maintenance page should show any available migration scripts.
Is the Event Espresso menu available, eg Registrations, etc? If so then the plugin has installed correctly (with or without migration).
Were the events active? If not then it is likely they are just hidden via the filtering system.

Data migration from EE3 to EE4 is only available from EE3 versions 3.1.36+
I would recommend creating a Full Site Back-up before continuing any further, just to be safe.
You’ll need to de-activate EE4, update EE3 to the latest version, then activate EE4 & migrate your data (you may also need to ‘Reset’ EE4 after updating EE3 to force EE4 to re-run migrations, you can do this via Event Espresso -> Maintenance -> Reset/Delete Date tab which will remove ALL EE4 data but leave EE3)
The reason for this is there have been database changes within EE3 from 3.1.27 to 3.1.36 which EE3 handles itself. Then EE4 runs the migrations based on the latest version of the DB.

Thanks for the prompt reply.
Your instructions worked Tony but I did get some “Warnings” after the migration about specific registrants, I then ran the migration again and everything seems to be fine. Weird.
Thanks!

If you still have the warnings saved somewhere we may be able to investigate further, although this depends on the warning itself.
Do you still have them saved?
