id like to migrate my client's site from joomla 1.5 to 2.5. all my content is in K2. i want to know if theres tool or option to help me migrate the content

getk2.org/documentation/tips-a-tricks/item/311-manually-migrating-k2-content-from-joomla-15-to-17
It will go to 2.5.1 now
There will be issues with templates and other things...

its simple.

1. export the DB tables for K2
2. change the prefix from (jos_ )? to your new db prefix if u have different
3. import the db tables
4. go in joomla 2.5 admin -> option=com_installer&view=database
5. guess you see an db error notice. Click fix. Normally its ok after this.
6. INSTALL the K2 v 2.5.4

Check that all items is there. Mine was just in order and fine with all dates etc..
