I am upgrading our website to Joomla 3 from 2.5 and we have a couple of web forms that we use for walk submission. I have used J2XML to copy articles across and having spent half an hour re creating one of out web forms discovered that you can export the
data from JSN Uniform using the configuration > Data > Backup/Restore option. This also had the benefit of coping across all the submission data. The only problem is that restoring the backup data into my Joomla 3 site overwrote that sample data I had previously install ( Installing the sample data warns that it will delete all existing data ). Is there any way I can get both the sample data and my Joomla 2.5 data install into my Joomla 3 site.
