Official support for Joomla 1.5 ended in September 2012.
Joomla 1.5 websites will, of course, still operate after this date but security vulnerability fixes may no longer be available and this could place your Joomla 1.5 website at risk.
Joomla 1.5 is difficult to support as extension developers concentrate on newer versions of Joomla and have dropped support for older versions.
Advice for Joomla 1.5 Website Owners
To keep websites secure, Joomla 1.5 website owners should update to the final release Joomla 1.5.26, apply end of life security patches if they haven't already and then migrate to Joomla 3.x as soon as possible.
Apart from official support, other advantages in moving to Joomla 3.x include new features such as esponsive tempates, tags, version control, improved security, PHP 7 support and custom fields.
The degree of difficulty in upgrading your Joomla 1.5 website to Joomla 2.5 will depend on a number of factors including the currently used template, other third party extensions and the content that needs to be brought across.
Migrating from Joomla 1.5 to 3.x
Joomla 1.5 is officially unsupported and potentially vulnerable if new security flaws are found and exploited by hackers.
Joomla 1.5 website owners can migrate directly from Joomla 1.5 to Joomla 3.x using a migration tool such as "SP Upgrade" or similar.
