Can anyone shed any light on how to upgrade/make compliant an old Joomla 1.5 site. The site uses VM 1.1.4 with a legacy UPS shipping module however, this no longer seems to be supported by UPS. The minimum TLS version they will support is version 1.2.
Any resources or suggestions would be most welcome. I'm googling but not finding anything related, likely due to the age of the site.
