I have an EE site that's based on the latest 1.x version and that has over 10,000 registered members (I tried a couple times to upgrade to version 2.x but it was a disaster). I now want to rebuild the site from scratch using the latest 3.x version and I want to move my 10k membership from the 1.x database to the 3.x database. Is that possible without creating a bunch of nasty side-effects for the new site?

I would read up on this https://docs.expressionengine.com/latest/cp/utilities/member-import.html Not sure if everyone will have to reset their password or not. ;~}

  • Thanks for the link. I wasn't aware of the utility until now. The instructions for how to use the utility are pretty minimal. Would I export from my version 1.x database to a XML file, then import that into the 3.x database? Does the 1.x version software even support the XML format for member data? Any additional info on this is much appreciated!

  • I have never actually used the utility. But I would assume, yes, dump your 1.x members table to an xml file, and then import into your ee3 install. Sometimes these things take a few runs at it to get everything to line up. Most database management tools, like Sequel Pro, can easily export to a varity of, including xml, file types.

  • Over the weekend I tried the membership utility and learned that it's going to be a bigger job than I thought, but I still think it's the best approach I have to solving my problem. After I've had more time to work with the utility I'll report back again sometime in the next few weeks.
