Dear support
I have an old jomsocial 3.0 on Joomla 2.5.14 with many users an their albums.
If I bye Jomsocial (supercharge) would it be possible to import these data? and how?
One problem that I have at the moment is this: photo thumbnails are very small, but the original picture is good. I do not know how the old admin did it, can you fix it with new Jomsocial?
Regards
if you install the ijoomla installer once you purchase then this will do a staged upgrade to the latest version, in regards to joomla that can be upgraded as per their upgrade process. Please be aware that the upgrade will remove all custom work you or the developer have changed in Jomsocial. Make sure you have good backups at every step of the way or even better make a test copy of your site and do that site first.
In regards to the avatars it sounds like someone has made a custom changes? if that is what you mean then you would loose that change and would need to recode it after the upgrade.
