And my SSI.php attached.

I also have a custom made theme with lots of custom things integrated.

My questions:

1. Which strategy do I have to make for upgrading to 2.0
2. Are all mods still available/working in 2.0
3. Will my theme still work in 2.0
4. Are there webmasters who have already dealed with this questions and succesfully upgraded to 2.0?

1. Use large upgrade package and you will be fine.
2. Search mod site
3. you may need to tweak it a little, upgrader will try to do it for you, it should work.
