Hello!
Could someone help me to understand how it's possible to migrate from 2.0.2 to 2.0.6 by files.
I cannot use installer 'cause I loose my current template with many fixes.
Thank you in advance!
If you used template overrides to show changed views then these will not be overwritten during an update, although there will need to be some template changes anyway due to alterations in priceDisplay function.
The alterations are detailed in http://virtuemart.net/index.php?option=com_content&id=416&tmpl=component
If you made the mistake of not using overrides then you could make copies of your current template files/css and compare/merge with the latest versions. You will, of course, make the update on a backup copy of the site.
