OK, let me restate the question... it was too early in the morning, with nowhere near enough tea consumed!!
I develop my site on my laptop, and then upload to the live webserver at a later stage.
Reading the manual in the previous post, the process now appears to be:
1. Export DEV database
2. Import to LIVE database
3. FTP any CSS files / images / etc
4. FTP changes in core/components
5. FTP changes in core/packages including the ZIP files
6. Update the path in the "_workspaces" table
Is my understanding correct?
Thanks (and apologies for all the questions of late!)
