A migrator plugin or an official tutorial on how to migrate RSGallery2 from a Joomla 1 environment til a Joomla 1.5 environment would be greatly appreciated.

Thanks in advance

I actually figured this out myself. Here is a short tutorial:

- Export the mos_rsgallery2 tables from you database through phpMyadmin or the SQL command line
- Save this as a .sql-file on your harddrive
- Edit the file using Notepad2 or Gedit or a similar text editor
- Find and replace replace latin1 -> utf8
- FInd and replace mos_ -> jos
- Copy the folder images/rsgallery from your 1.0.x-installation to the new installation
- Import the redited sql-file into J! 1.5
- Install the component. During the installation it should see the tables and check them for you.
