I’ve reviewed our email history… there was nothing I could find in regards to a failed update and you having to export and reload the database.
However…
I did find where you asked if there was a way to identify changed entries from a specific date because an individual who was to keep track did not and you need to migrate those changes to another site.
My suggestion was to export the data from the source site to the site needing updated. I wonder if this is what you are remembering??? If that is, that had nothing to do with updating Connections.
Any way, on to your question…
I’ve never tested upgrading from such an old version. Technically it should be fine, but I would proceed with an abundance of caution. I personally would make a backup of the file of the version of Connections you are using. I would also make duplicates of the Connections tables in the database. That way both could be rolled back in case of an issue. Alternatively, you could use a plugin to backup the site and database. That way is something goes wrong, you could just restore the entire site and database. That is more of using a hammer instead of a scalpel approach but would work.
Our email exchanges indicate that you may have edited the files for the template you are using. Depending on those changes, the template may or may not be compatible.
If you want, I could perform the upgrade for you as a service for a fee. Let me know.
Not sure if this helps, but hope it does!
