Migrate & Update Gallery (menalto) version 2.3 to version 3

Hi there, I need a installed gallery 2.3.0 installation updated to 3.0.2 (latest version). It probably needs to be updated to 2.3.1 first and then to 3.0.2 to make this transition OK. Gallery is an open source tool for making galleries, see http://gallery.menalto.com. The gallery is hosted IN a magento webshop hosting (for example: [login to view URL]), I think that makes no difference but just mentioning it anyway. The whole script + database is on a new server now. Main reason for upgrade: Our new server does has php 5.3.6 and the old gallery 2 installation is not compatible with this. The new gallery 2.3.1 IS compatible, and version 3.0.2 is also compatible, so I want to upgrade to latest version now. Your job is to do the upgrade, and get the new gallery FULLY working with the same pictures and albums still in tact as in the old gallery. Details: The gallery has 69 main albums with over 15.000 pictures. Please ONLY bid if you have experience with this OPEN SOURCE GALLERY script!!! If you bid, please send message with confirmation that you know how this gallery works and that you can update it. Bids with provable experience with this gallery script are my first choice.
