Migrate Backup to new Domain

Hi everyone,

We used UpDraftPlus to backup a blog last year. Since then, we’ve wanted to bring it back on a new instance of WordPress.

The original blog was located at margaretbiggs.com/blog/

We now want to make it live at caulfield.co/margaretbiggs/blog/

Is there any way to do this?

Background –

We’re shifting hosting providers and cannot reinstall it at the original domain/subdomain until we do, but would like to begin building the new site on a development domain in the meantime (caulfield.co/margaretbiggs).

Thanks!
Will
