Change theme and remove previous?

Hello, My website has already a theme.

Do I need to upload the new theme before or after I remove the previous theme? I use King Composer as well. Should I desactivate it before?

Hi

If you are talking about the same theme but you want to update then I would like recommend you to check the documentation, hope you will get help how to update the theme.

If you are talikng about new theme then I wuld like to recommend you to check the documentation how to install the theme and theme bundle plugins. and important thing in this case if you already have a theme and you have activated the theme with purchase code then you have to deactivate old theme (in this case you have to check documentation or have to contact author how to deactivate the previous license so that you can use that license again when you will need). After deactivate the old theme you can active the new theme and you will need purchase code for the theme registeration mean activate with license.

If you need help You can contact theme Author and let them know How to Contact your purchased theme Author, theme author will be happy to assist you.

Thanks
