Migrate to new website

Hi Kara,

I have not tested this, but simply updating your Joomla site from version to version 4 should be enough. Just use the core Joomla Update component.
Now, if you want to move to a clean installation then things are simple for Showtime Image Gallery:

1. Install Showtime Image Gallery to the new site.
2. Copy #__showtime_galleries and #__showtime_images database tables from your old site to the new one.
3. Copy all the files under /media/showtime/storare from the old site to the new one.

This should be enough for bringing in Showtime Image Gallery but not Contacts and their custom fields.
I cannot tell for sure if CSVI Import and SP Transfer would do the job. Probably you need to ask their developers about this.

An other approach would be to duplicate your current site and then use the core Joomla Update component to update to Joomla 4. After that just remove any extensions or content you don't need. The result would be like a fresh Joomla 4 installation.
I think that overall this is the easiest and more safe approach but it's all up to you.

Please let me know if you need help with this.

Regards
