I had to copy the database across manually, since the duplicator database copy had only copied 11 of the tables, and I also had to edit wp-config because it wouldn’t let me change my wordpress address via the dashboard afterwards. It wasn’t a big site I was moving either.

I also had to enable php zip on my server, which wasn’t hard, but did add to the faff a bit.

Easier than manually downloading and uploading it all by SFTP, but I think in retrospect it might have been quicker to use the command-line, even though I’m a bit rusty and would have to look things up.
