One thing to point out though is I don't think you can copy over any new fields you create in  Sandbox into your production instance. We did a Marketo implementation last fall and we started with testing everything in Sandbox first. We created several net new fields in the Sandbox for testing purposes and were told by our Marketo consultant that there was not a way to push those fields into our production instance, and instead we would have to manually create them. ...

Because of that, in the past I've just used Zapier to integrate the event registration data in to Marketo and that's worked pretty well.    We did recently evaluate upgrading for the full Marketo integration at the beginning of the year and it seems pretty robust and is something we would probably consider as live events start to pick back up for us. We decided to keep running our virtual events and webinars on GoToWebinar because even with the Bizzabo - Marketo integration piece, Bizzabo doesn't have the full integration capabilities for webinar programs like a GoToWebinar, On24, or Cvent because it's not a native Marketo built integration. ...

Unfortunately, it's too late in the game to make any changes at this point.

At this point, I'm just looking for any tips/best practices from individuals who have performed a similar implementation. Thanks. ... View more
