Hi @awr10e
Thanks for reaching out. Let me help you with this one.
Would it be possible for you to set up a staging version of your live site and try to re-do the migration from there?
Here are the steps to revert and re-do the migration:
- Update to the latest versions of The Events Calendar and Events Calendar Pro.
- Remove any un-needed draft events and empty the Trash.
- Activate only our plugins and use the 2020 theme.
- Make sure server-side caching is disabled temporarily while you’re migrating your events.
- Install and activate the Code Snippets plugin.
- Add this snippet and run it once (be sure it does not stay activated).
- Go to Events > Settings > Upgrades and go through the migration process again.
Please re-do the migration on your staging site to avoid unnecessary downtime to your live site.
Let me know how it goes.
