Upgrading from J3 Free to J4 Pro

Hi there,

Please could you give me some help with upgrading to the Joomla 4 Pro version of SIGE?

I have just migrated to Joomla 4 and tried to install the Pro version but it makes a lot of errors and breaks the site. Should I uninstall the old J3 free version before installing the new J4 Pro version?
If I do that, will I have to re-create all my gallery pages?

Currently, as far as I know I am still using the free Joomla 3 version of SIGE which I was expecting to stop working when I went to Joomla 4 - but it's still there and working fine!
eg. sandhurstgardendesign.co.uk/planting

I want to make sure everything stays working and up to date, plus I already paid for the J4 version so I'd like to get that working properly. Many thanks for any help you can give.

Best wishes
Leila
