Import attendees and events after EE3 to EE4 upgrade

As part of a website redesign, I am planning on upgrading from EE3 to EE4. However, the redesign will be built on a development environment. When the redesigned site is ready to go live, is there a way to import all current attendees and events from their current production environment into the development environment?

Hi there,

Yes, it’s possible but not really via an ‘import’.

You would need to copy the EE3 tables to the new site’s database and then run the EE4 migration to migrate that database over to EE4. All of the EE3 tables use {prefix_}events_* for the table names, so you copy them all over to the new site just before the migration.

Note the EE4 migration only works on the initial activate of EE4 on the site, but you can ‘reset’ EE’s tables and it will run the migration on the next activation but you’ll lose any EE4 data you have on the site at that time.

So you develop the new site using EE4, reset EE4 so all EE4 data is removed, import the EE3 tables and activate EE4 to migrate all of the data.
