Problem during upgrade
During the upgrade from version 2.2.16 to version 2.3.7, it tells me I must delete the databases. Does anyone have a solution to upgrade without deleting the data?

 

I need to add API IMEICHECK to xenForo

First, enable those two recommended functions on your server.

Then, try upgrading to 2.2.17.

Next, disable the XF 2.2 addons and styles, as they will definitely not work on XF 2.3.

Finally, upgrade to 2.3.

Remember to back up your data before doing so.
